2014-03-05add btrfs module quirk for linux 3.14WorMzy Tykashi1-1/+1
This patch adds in some extra hackery to make sure that users with btrfs root filesystems don't end up with unusable initrds due to the following change made upstream [1]. TL;DR: The btrfs module has dropped it's libcrc32c dependency, so mkinitcpio no longer pulls in the crc32c module necessary for the btrfs module to be inserted. The crc32c module was only pulled in previously due to mkinitcpio hackery [2], so extra hackery now seems like the logical path. This problem can be experienced by using linux-mainline on an Arch machine with a btrfs root filesystem. Besides from this extra hackery, an alternative workaround would be for users in this situation to add crc32c to their MODULES aray in their mkintcpio.conf. Of course, this needs to be done ahead of the linux-3.14 upgrade for them to avoid the problem (assuming none of their other modules depend on libcrc32c).

2014-03-01Always use the --target flag with findmntDave Reisner2-4/+4
Prevents problems with bogusly named filesystems, e.g.: mount -t tmpfs / /mount/point Fixes FS#39090.
2014-01-04sd-shutdown: add kexec binary if it's availableDave Reisner1-0/+4
2013-12-24lsinitcpio: remove nonexistent showconfig longoptDave Reisner1-1/+1
Should have been removed as part of previous commit, as this was clearly just a typo.
2013-12-24include missing longopt --config in arg parserDave Reisner1-1/+1
Reported in FS#38264.
2013-12-22Add -l flag when using lz4 compressionDave Reisner2-4/+14
This isn't documented, but it's needed since the kernel lz4 support is based on the original streaming format and not the newer default. Use -l to force the legacy codec. Fixup lsinitcpio to support the older format, and, add a warning when the newer format is detected. Who knows when this will be "resolved" ...

2013-12-16Strip a leading 'v' from the git tag when generating the version numberv16Thomas Bächler1-1/+1
2013-12-15Add sd-vconsole hook.Thomas Bächler1-0/+68
This hook works together with the systemd hook from the systemd package and requires the add_systemd_unit function. It launches systemd-vconsole-setup.service in initramfs and is especially useful to unlock encrypted volumes in initramfs.
2013-12-15Install mkinitcpio-generate-shutdown-ramfs.service as a static serviceThomas Bächler2-4/+3
Pretty much everyone benefits from this service, as it is always better than having no shutdown-ramfs. If someone puts their own shutdown-ramfs in place, it will likely be done by initramfs and this service will be skipped automatically. In more obscure situations, it can still be masked.
2013-12-15Add a tmpfiles.d configuration file to create /run/initramfs.Thomas Bächler2-1/+6
2013-12-06prevent calling a preset from a presetDave Reisner1-1/+6
This is surely a configuration error as it's an infinite loop.
2013-12-01remove legacy search paths in /lib/initcpioDave Reisner2-4/+2
2013-12-01Load build and run hooks from /etc/initcpioDave Reisner3-3/+11
This lets users shoot themselves in the foot more easily, as they can put their own modified hooks into /etc/initcpio/{hooks,install} to override those shipped by the distro in /usr/lib/initcpio. To make debugging easier, include the full path of the hook being used when mkinitcpio runs in verbose mode. Implements FS#37796.
2013-11-27sd-shutdown: don't fail after kernel updatesDave Reisner1-1/+1
When the module directory matching $(uname -r) cannot be found, generation of the shutdown ramfs aborted: systemd[1]: Starting Generate shutdown-ramfs... mkinitcpio[1944]: ==> ERROR: '/lib/modules/3.12.1-1-ARCH' is not a valid kernel module directory systemd[1]: mkinitcpio-generate-shutdown-ramfs.service: main process exited, code=exited, status=1/FAILURE systemd[1]: Failed to start Generate shutdown-ramfs. systemd[1]: Unit mkinitcpio-generate-shutdown-ramfs.service entered failed state. Tell mkinitcpio that we do not wish to add any kernel modules.

2013-11-27mkinitcpio: Allow building an image without modulesThomas Bächler4-3/+10
The '-k none' switch prevents mkinitcpio from adding modules to the image and keeps it from bailing out when it cannot find any.

2013-11-24Add mkinitcpio-generate-shutdown-ramfs.serviceThomas Bächler3-1/+32
When enabled, this service generates an "initramfs" that systemd pivots to on shutdown to ensure clean umounting and shutdown of loop and dm devices. The actual work is done by systemd-shutdown.
2013-11-24mkinitcpio: Improve output when -d option is used.Thomas Bächler1-3/+7

2013-11-24mkinitcpio: add -d optionThomas Bächler2-22/+28
The -d (--generatedir) option writes the root of the generated image directly to the specified directory. Useful for generating a shutdown-ramfs with mkinitcpio -d /run/initramfs/.
2013-10-21lsinitcpio: separate decompression from archive readingDave Reisner1-3/+3
This essentially reverts 306dcbd7b21f8a680 which foolishly assumes that kernel and libarchive decompression support stay in sync. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-09-26kernel-install: add hookTom Gundersen2-0/+15
This will allow systemd's kernel-install script to generate and install an initrd as per the freedesktop boot loader specs. See kernel-install(8) for details. Notice that 'profiles' are not used. This will eventually be hooked up so that calling "make install" from a kernel build will do the right thing. Signed-off-by: Tom Gundersen <teg@jklm.no>
2013-09-25mkinitcpio.conf(5): mention lz4 compressionDave Reisner1-3/+3

2013-09-24autodetect: read modaliases from uevent filesDave Reisner2-7/+8
As suggested by Harald Hoyer, this is more accurate for the sake of following where udev gets its modaliases from. In some rare cases, it may even be more complete than scraping the raw modalias files. Also, introduce a wrapper around modprobe so that the options passed are never ommitted, or wrongly specified. In this case, a subtle bug with the -r flag is fixed due to using the wrong variable with modprobe's -d flag. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2013-09-09add mkinitcpio version marker in buildroot creationDave Reisner2-3/+3
It doesn't make any sense that this was added during the final image creation. This fixes a subtle bug that would manifest itself if the user archived the build root manually. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-09-07lsinitcpio: return success based on echo, not hexdumpDave Reisner1-0/+1
The impetus for doing this was a bug in util-linux's hexdump which never saw a release. For uniformity, simply echo an empty line here. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-09-07lsinitcpio: add support for lz4 compressed imageDave Reisner3-1/+8
Note that this requires a very recent version of lz4 utilities as it uses lz4, and not the original lz4c tool, in order to be command line API compliant with other compression tools.

2013-08-28mkinitcpio: preserve permissions if run as rootDave Reisner1-1/+5
Running as non-root is usually for my own dev purposes, but someone might do this and be surprised when a directory/file that needs permissions other than root isn't preserved. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-08-28rely on libmount defaults for file locationsDave Reisner2-2/+3
Using --tab-file for findmnt calls is redundant if we can rely on the defaults. Sanitize the environment from any LIBMOUNT_* variables so that we can be sure of what file we're reading. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-08-28autodetect: search for /usr explicitly using -TDave Reisner1-1/+1
Doing this oddly results in findmnt never stat(2)'ing the target directory, which might be problematic with stale NFS mounts and maybe autofs. Fixes FS#36629, I suppose. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2013-07-01rdlogger: log messages which would have been hidden by quietDave Reisner2-1/+7

2013-06-25init: allow for logging of early userspaceDave Reisner3-2/+176
This introduces support for the rd.log and rd.debug kernel command line options, which log early userspace activity to /run/initramfs/init.log. Code is largely inspired by Dracut's implementation of early userspace logging, but without needless complexity and redundancies. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2013-05-02mkinitcpio: ensure ERR trap propagates to install_modulesDave Reisner1-0/+2
Without this flag set, errors in install_modules are ignored, and mkinitcpio potentially exits without complaining about build problems when foolish people run out of disk (presumably after using /tmp as a build directory). Fixes FS#35037. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
