2012-06-01move running of hooks to separate functionDave Reisner2-42/+39
This allows us to declare sourced variables that we want to shield from stomping on our config variables, and without needing to use a subshell. Incidentally, this also fixes FS#29992 in a more permanent way. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-30update comments in configDave Reisner1-8/+5
This really should be moved into a man page. FS#30042. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-30add_full_dir: properly handle symlinks and empty dirsDave Reisner1-2/+5
Note that we're intentionally very liberal about what we accept for symlinks, and don't actually care if the target exists. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-19manpage: remove explcit author list0.9.0Dave Reisner2-11/+3
This is what git is for. At this point, I've (re)written the majority of the page anyways. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-19manpage: expand doc on build and runtime hooksDave Reisner1-10/+98
Fully document the recommended API for install hooks, and the various hook points available for early userspace hooks. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18init: add timestamp at start of initramfs if binary existsTom Gundersen1-1/+8
This will allow us to tell how much time was spent in the initramfs, which might be good for working on optimizations and making sure we don't regress. If a binary able to produce the timestamp is not installed this is a noop. I'll post separately an install hook to the systemd package that will install systemd-timestamp. However, it would be trivial to replace this by an independent implementation if people want to use this without systemd. With this patch I get the following on my (ancient) laptop: $ systemd-analyze Startup finished in 294ms (kernel) + 2684ms (initramfs) + 15741ms (userspace) = 18720ms FWIW, 1 second is spent on inserting the needed modules, and 1.5 seconds on mounting the rootfs (mounting btrfs is slow!).

2012-05-18usr: add usr mounting as a late running hookDave Reisner5-12/+33
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>
2012-05-18init: remove hardcoded udev startup/shutdownDave Reisner1-16/+1
This will be handled by udev's run_earlyhook and run_cleanuphook, respectively. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: Always show extraction timeDave Reisner1-2/+2
Even for uncompressed images, estimate the work being done to extract to ramfs. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: add support for listing new hooksDave Reisner1-21/+20
Read this out of the image config for -a output. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: extract the image to a tempdirDave Reisner1-18/+45
We read the image a number of times. Extract the image to a temp directory so we can just extract it once and use the filesystem to our advantage. This requires a temp dir which we can nuke on an EXIT trap, but the whole operation is sped is a bit, especially for larger images. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18buildsys: fix clean targetDave Reisner1-1/+1
We don't ship compressed manpages, and this never touched lsinitcpio's generated page. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18shutdown: convert to cleanup hookDave Reisner1-1/+2
Run this later in init where we can delete the modules from the ramfs before copying the image over to /run/initramfs. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18shutdown: package as 644, install as 755Dave Reisner2-1/+1
There's no need to keep this mildly dangerous script executable on the filesystem. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18init: add support for early, late and cleanup hooksDave Reisner1-2/+7
This adds support for three more rounds of hooks during early userspace. Users can define a 'run_latehook' in their hook script similar to the declaration of 'run_hook' (which continue to run at the same point in execution). These are run in the same order as the original "early" hooks shortly after root is mounted. Additionally, 'run_cleanup' hook can be defined which will run right after the late hooks. These scripts are executed after mounting root in reverse order of how they're clared in mkinitcpio'c config. These late running hooks should take care of things such as: - mounting /usr (possibly encrypted) - moving config to the real root (mostly for liveCDs) - shutting down previously started daemons (e.g. udev or dropbear) Finally, we add run_earlyhook which is run as soon as possible. There will likely be only a few subscribers to this, but udev will certainly be one of them, as it needs to be started as early as possible when present, to avoid problems with firmware loading.

2012-05-18mkinitcpio: write image config after install hooksDave Reisner3-15/+22
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>
2012-05-18init_functions: move running hooks to separate funcDave Reisner2-15/+18
Abstract this out to the init_functions file, and allow this function take 2+ parameters -- the hook name to be run, a user friendly short description, and then the list of hook files to source from. While we're at it, take advantage of the fact that hooks are now installed with executable perms. If a hook isn't marked excutable, we skip it, thereby removing our eval hack. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18init: correct trimming of earlymodules and MODULESDave Reisner1-5/+2
This never worked properly and only "fixed" the stupid bug that found an edge case when either of these vars contains nothing more than a single space. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-18functions: introduce add_runscriptDave Reisner2-4/+45
This function adds a runtime script to the /hooks directory on the initramfs image. Note that this function will also install hooks with executable permissions for use by a later change to early init. With this commit, there are now methods available which can be used in place of the MODULES, FILES, BINARIES, and SCRIPT variables, as we now offer error checking on the add_* functions. Usage of the variables is deprecated, and these will no longer be read in a future version of mkinitcpio. This commit also lays the groundwork for the addition of more early userspace hooks. Runtime hook files are parsed for specific functions and variables (not yet used) are populated. These will eventually be written to the image config so that early userspace knows exactly what to run. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-16functions: introduce add_checked_modules and add_all_modulesDave Reisner1-2/+50
Instead of returning a list of modules which the caller should then add themselves or stuff into the MODULES string, call add_module for each candidate. This is basically a different wrapper around all_modules. DEPRECATION WARNING: This commit marks checked_modules as deprecated. Although it is not slated to go away, direct usage of all_modules is strongly discouraged. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-16move -g option checking to parseopts loopDave Reisner1-9/+5
Avoid any delay in checking this option, as it only serves to fragment the logic. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-16functions: move --try logic into add_moduleDave Reisner1-13/+16
Allow add_module to detect trailing ? characters for ignoring errors rather than passing -t or --try to add_module. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-16functions: remove get_dirname and get_basenameDave Reisner1-13/+1
A lot has changed since 643e98eeb42677 when these functions were implemented, and there is exactly 1 case of get_dirname left, and no calls to get_basename. Remove these, and use a PE in place of the remaining call. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-16refactor error tracking in build hooksDave Reisner2-8/+14
Rather than catching errors solely from parse_hook via an ERR trap, implement a RETURN trap which catches all errors from the core add_* functions. In the future, this may mean that support for MODULES/FILES/BINARIES within hooks goes away, and those variables remain only in the config. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-16mkinitcpio: separate logic to resolve kernel versionDave Reisner1-8/+22
Rename get_kernelver -> resolve_kernelver, and ensure that it only does what it's name advertises. Introduce find_moduledir to locate the corresponding module directory in /usr/lib or /lib. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-05-12mkinitcpio: remove --basedir optionDave Reisner8-88/+45
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>
