Hi! I'm flooding your mailboxes again. There's been some changes, so I'm resubmitting the stuff I'm happy with (and need to stop refactoring). The latest is always available on github, but I'll do my best to keep these 12 frozen unless I find a showstopper. Major patches to note are: 2/12: deprecates install, changes every install hook to have a 'build' function instead. 8/12: kills gen_init_cpio. it's a bit of a scary large patch. 12/12: allows specifying a kernel as a path, e.g. /boot/vmlinuz26. This one is, imo, important to have before linux 3.0 is released. Patches 5 and 9 are refactors of some of the install hook API which yield some tasty speedups beyond what patch 8 offers. The rest is assorted cleanup and bashification. Also, there's still more to come, but I'll hold off until this gets digested. d functions | 290 ++++++++++++++++++++----------------------- hooks/dmesg | 5 - install/autodetect | 2 +- install/base | 7 +- install/btrfs | 2 +- install/consolefont | 2 +- install/dmesg | 18 --- install/dsdt | 2 +- install/filesystems | 2 +- install/fw | 2 +- install/ide | 2 +- install/keymap | 2 +- install/memdisk | 2 +- install/net | 2 +- install/pata | 2 +- install/pcmcia | 2 +- install/resume | 3 +- install/sata | 2 +- install/scsi | 2 +- install/sleep | 2 +- install/udev | 2 +- install/usb | 2 +- install/usbinput | 2 +- mkinitcpio | 134 +++++++++++++-------- mkinitcpio.5.txt | 7 +- mkinitcpio.conf | 9 +- mkinitcpio.d/example.preset | 2 +- 27 files changed, 246 insertions(+), 265 deletions(-)

Modify the sed filter to remove PIC addresses and ignore the first line which will always be the vdso. Also remove the tls filter, as glibc has had threaded support mainlined for many years now. If a user has a glibc this old, we don't have support for them elsewhere (udev, kernel). We also cleanup the logical flow through this function and remove a lot of cruft that would always return true, or that didn't quite make sense.

New subject: [arch-projects] [mkinitcpio][PATCH 05/12] functions: refactor add_module

Simplify and fix a few bugs in the process. We rely solely on modinfo for obtaining information about module location, dependencies and firmware. Add a small wrapper function for modinfo that will always specify our $BASEDIR and $KERNELVERSION for us. Also, kill off HAS_MODULES. Since we have ADDED_MODULES, which contains all currently added modules, we can count the elements in this when it comes time to decide to create depmod files.

New subject: [arch-projects] [mkinitcpio][PATCH 06/12] functions: remove add_device

This was only ever used in the base layout, and it's not needed. devices will be present if we're using devtmpfs, and created for us by init if we mount on tmpfs. Also, this is part of our move towards using bsdcpio instead of gen_init_cpio, and as a side effect we can no longer support this. Any devices that need to be created should be done so by the runtime hooks, not the install time hooks.

This is a departure from using gen_init_cpio, which proved to be a huge bottleneck in performance. Tests for existance change from being a call to grep, to a simple shell test.
