2012-03-26shutdown: disassemble devices on shutdownDave Reisner2-1/+65
sysfs contains enough information about block devices to be able to determine the order of stacked devices such as lvm, raid, or crypto. By looking at the device symlinks from the holders/ attributes of a block device, we can walk down each device chain until we reach the most descendant device. For each of these devices at the end of a chain, detect its type and perform the appropriate action to disassemble it. Then, walk back up the device chain, disassembling each parent device. To save ourselves some pain and make sure we're fairly accurate, lsblk is brought in for detection of device types.

2012-03-26shutdown: add vim modeline, fix whitespacingDave Reisner1-13/+15
Make this consistent with the rest of the codebase. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-24Makefile: simplify 'make dist' target0.8.5Dave Reisner1-9/+6
- Use git-ls-files and bsdtar to create the archive rather than using git-archive and an temporary directory. - Remove the tarball target. 'dist' is more common. - Remove the 'clean' dependency from dist. Our dependencies are sufficient higher up that touching the Makefile or the asciidoc input will trigger a doc rebuild on changes.

2012-03-24init_functions: fix tag resolution w/o udev rulesDave Reisner1-10/+9
The combination of the udev+mdadm hooks plus a tag based root= would cause resolve_device to fail because it immediately looked for a udev symlink which would never be created. The proper fix is to get rid of the mdadm hook and to always use mdadm_udev (which should be merged into mdadm), but this might come back and bite us again. The new solution doesn't assume that udev rules exist and tries blkid first. If the device doesn't (yet) exist fall back on a udev symlink if udevd is running.

2012-03-24natively support locale.conf and vconsole.confDave Reisner2-7/+26
This is implemented for the keymap and consolefont hooks. It's done in such a way that vconsole.conf and locale.conf will override and supplement rc.conf. Implements FS#29022. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-24init_functions: support fsck.mode= cmdline parameterDave Reisner1-0/+6
Possible options are 'skip' and 'force' which are synonyms for fastboot and forcefsck, respectively. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-24init_functions: avoid special treatment for forcefsckDave Reisner1-2/+1
I don't want to make a habit of treating cmdline opts as special if they don't need to be, and this is a case where some simple PE magic can be substituted. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-03-11hooks/resume: refactorDave Reisner1-25/+37
- cleanup syntax, style - use case to detect syntax (avoid problems with vanilla devspecs containing a ':') - support LABEL=/UUID= syntax for vanilla hibernation (FS#28504) - be more verbose about errors Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-06mkinitcpio: force UID/GID 0 for files written to imageDave Reisner1-1/+1
This fixes a strange edge where-in a user creates an image as non-root and attempts to boot from it. Any setuid binaries (such as mount) will fail, as the ownership is preserved. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-04mkinitcpio: dedupe MODPATHS array before installation0.8.4Dave Reisner1-1/+2
The only reason this has to be done is because of the Kconfig option that reuses the ext4 module for ext[23], thereby aliasing ext[23] to ext4. This is (currently) the only case in the whole kernel where valid module names magically become aliases. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-04init: add informational output about mountingDave Reisner2-0/+2
Applies to both the real root and any device that's mounted on /usr Signed-off-by: Dave Reisner <dreisner@archlinux.org>

Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-04add support for HOOKDIR/INSTDIR as arraysDave Reisner7-54/+83
This is a really ugly patch, but allows mkinitcpio to read hooks from multiple locations, namely: /usr/lib/initcpio/{install,hooks} /lib/initcpio/{install,hooks} Preference is given to the first, and all files included with mkinitcpio are moved there. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-04init_functions: lazily resolve UUID/LABEL tagsDave Reisner1-5/+22
Relying on blkid to do tag resolution will fail when the root device doesn't yet exist. This is, of course, bad for USB root devices. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-03install/fsck: use fsck.ext4 for ext[234]Dave Reisner1-2/+12
e2fsprogs makes a lot of hardlinks for its fsck tools. If ext[234] is detected, add the fsck.ext4 binary and add symlinks. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-27install/autodetect: avoid adding empty rootfstypeDave Reisner1-5/+5

2012-02-22autodetect: resolve guessed filesystem modulesDave Reisner1-2/+8
Trading out modinfo for modprobe allows us to detect filesystems like ext2 and ext3 which might be aliased to ext4 in the case of Kconfig CONFIG_EXT4_USE_FOR_EXT23 being enabled. Maybe this catches other insane corner cases, too. Since we now treat this as possible aliases, we also need to be mindful of the fact that it could resolve to multiple module names. Assign the output as an array to respect this. Fixes FS#28569. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-20lsinitcpio: trim binaries during discoveryDave Reisner1-3/+3
Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-20lsinitcpio: detect kver separate from modulesDave Reisner1-6/+4
mkinitcpio will always create /lib/modules/$kernver/kernel in the image, so we can use this to detect the kernel the image was built for, even if the image contains no modules. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-17mkinitcpio: unzip modules before image compressionTom Gundersen1-0/+3
This increases compression efficiency, which might be useful on an image containing a lot of modules. For the usecase I had in mind, this reduced the size by about a quarter. Signed-off-by: Tom Gundersen <teg@jklm.no> Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-14mkinitcpio: install all modules to a single dirDave Reisner1-6/+2
depmod doesn't care where modules are, within reason, and separating modules into the respective hierarchies only serves to irritate users who go looking for modules in the rootfs (aka me). Forget all this and dump everything into the kernel/ dir. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-14mkinitcpio: catch more buildtime errorsDave Reisner1-3/+6
Move the unsetting of the errtrace and ERR trap flags to after the image has been built. This lets us capture errors during module installation to the build root and the call to depmod. Either of these steps failing could be hazardous and should prompt a failure. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-02-11autodetect: refactor raid device detectionDave Reisner1-6/+22
FS#10061 still isn't dead, its just resting: https://bbs.archlinux.org/viewtopic.php?pid=1056003 An strace from a helpful user shows that our mdadm call is trying to open a block device and the call never returns: open("/dev/sdb", O_RDONLY|O_DIRECT|O_LARGEFILE Fix this by only scanning explicitly the block devices we're interested in, found via sysfs. This is an all around win for everyone, especially users who have mdadm installed without any need for it. This changes some of our assumptions about the environment: - the mdadm binary exists when we find md devices in /sys - the user running mkinitcpio isn't any specific UID or part of any particular group, but merely has read access to the block devices we're about to scan.

Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-29init: use fastboot, not skip to avoid fsckDave Reisner2-1/+6
Move this logic inside fsck_device as well, so that fastboot skips a possible fsck on the /usr partition as well. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-29init_functions: avoid using fsck_ret to check 0Dave Reisner1-7/+7
our fsck_ret function would always return true when passed 0, which clearly isn't what we want. Use a simple string compare instead. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-28function: avoid applying --try to all modulesDave Reisner1-3/+3
An error in logic here would cause the --try flag to be passed to all modules after the first, if a hook added modules ending with a '?'. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-28autodetect: remove hack to exclude {ata,ide}-genericDave Reisner1-1/+1
In particular, skipping ata-generic causes some macbooks to not boot. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-28avoid absolute paths in add_binary callsDave Reisner4-9/+9
This makes us more resilient against path changes -- add_binary is smart enough to resolve the path for us. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-01-28shutdown: make reboot the default actionDave Reisner1-5/+2
systemd passes 'kexec' on 'systemctl kexec' which isn't being caught. Catch the few possible verbs for a halt, and let everything else default to trying a kexec; falling back on a reboot. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-01-13init: drop support for non-devtmpfs0.8.2Tom Gundersen1-12/+1
udev does not support this as of udev-176, so there is no point in pretending it will work. This also drops devtmpfs_mounted=1, so any custom hooks that use this would have to be updated (no official hooks are affected). Signed-off-by: Tom Gundersen <teg@jklm.no>
2012-01-13Update PS1 ramfs -> rootfsGerardo Exequiel Pozzi1-1/+1
This is cosmetic change, but using rootfs is more correct than ramfs. [Rootfs is a special instance of ramfs or tmpfs, if that is enabled] Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

2012-01-13init: mount separate /usrDave Reisner2-1/+10
Use findmnt to detect the existance of a separate /usr partition existing in the real root. If it does exist, fetch the options for it and mount it. This currently makes a lot of assumptions and won't be very friendly towards something such as a dm-crypt device. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-01-13base: add findmnt as a part of the base layoutDave Reisner2-1/+2
This is required for mounting a separate /usr. While the shutdown hook is essentially a soft requirement for a separate /usr, we shouldn't break init. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-01-12dsdt: remove hook. this has been defunct for yearsDave Reisner1-14/+0
Refer to commit 9a9e0d68555 in the kernel where Linus removes this and says "to be revisited later". The only option (currently) is to built this into your kernel image. Suggested by FS#27906. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
