2012-07-15initalize buildroot later, and out outside of hooksDave Reisner1-10/+1
mkinitcpio needs to be able to more tightly control the layout of the image. By moving this outside the control of the base hook, it's more reasonable to believe that a drop-in replacement for the base hook could be written, as it now only contains the utilities required for the /init that it provides. Being that initialize_buildroot is outside of a hook, we can make "raw" calls to coreutils that create the directories and symlinks, saving some overhead and forking. This also symlinks /usr/local/{lib,bin} into the common /usr/lib and /usr/bin, respectively, so that there's always a way to override libs and bins, and they're automatically pulled into our strict early init path of /usr/bin. Finally, we lump all this generally a little "later" in the early setup. This addresses an unseen "bug" wherein an extra temp directory that never gets used is created when leveraging a preset.

2012-07-15add 'strip' install hookDave Reisner1-0/+32
Mostly a convenience for myself, and anyone else who runs builds of things like util-linux or kmod, where having debug symbols on these libraries can add a large amount of weight to the image. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-18usr: add usr mounting as a late running hookDave Reisner3-1/+17
Mount separate /usr partitions voluntarily, as a late running hook. This is an unfortunate patch that will no doubt result in some hatemail, though it won't thoroughly break anyone to the point of not booting. As a side effect, findmnt is no longer a requisite of the core /init, so move it to the shutdown and usr hooks where it's required. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-18mkinitcpio: write image config after install hooksDave Reisner1-15/+0
Break this out of install/base into a separate function. We need to be able to read from the RUNHOOKS array to accurately specify which hooks to execute at runtime. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-12mkinitcpio: remove --basedir optionDave Reisner4-10/+10
This option is just a bad idea. Initramfs creation is too important to get wrong, and running it from outside the root FS has too many gotchas, the worst of them being: - where do you pull hooks from? - how do you resolve binary dependencies within the root? In general, dealing with the extra luggage of the base directory makes the codebase more complicated than it needs to be (see all the '_' prefixed functions which are called from add functions). In favor of simplifying the code, and making it more maintainable, kill this off and force the sane option of chroot'ing into an install if the need arises.

2012-05-02fsck: try harder to find fsck binariesDave Reisner1-2/+2
fsck binaries might be outside of /sbin -- glob on all the common paths. This almost matches what we use for util-linux's fsck search path, but we omit the oddball /sbin/fs and /sbin/fs.d directories. Note that this only affects non-autodetect images, since autodetect resolves fsck helpers directly by name. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-04-02autodetect: simplify mdadm autodetectionDave Reisner1-23/+5
Everything we need to know about the devices is already in sysfs attributes for the md devices. Read any found nodes for raid levels and sort them into our whitelist. This removes the need for root in order to "scan" arrays. More code churn on top of d11ba00. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-28fsck: leverage blank /etc/fstab included by baseDave Reisner1-1/+1
Since 3b18c9cd we have a blank /etc/fstab in the image. This is also forward thinking for the next release of util-linux (2.22), where fsck complains loudly about my filthy hack of using /dev/null as /etc/fstab. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-03-26shutdown: disassemble devices on shutdownDave Reisner1-1/+1
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.

2012-03-04add support for HOOKDIR/INSTDIR as arraysDave Reisner2-5/+5
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.

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>
2012-02-11autodetect: 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.

2011-11-29busybox: create symlinks manuallyTom Gundersen1-0/+5

2011-11-29move all binaries to /usr/binTom Gundersen1-1/+5
Add compat symlinks from /bin, /sbin and /usr/sbin, so nothing is lost. This will make sure that it is not possibly to install two different versions of the same binary in PATH. The main usecase of this is that we want to be able to override any symlink provided by busybox by adding a binary by the same name. With this patch we don't have to worry in case the busybox symlink and the binary we add are in different directories; the last binary to be added always takes precedence.
