"quiet" is already used by the kernel to avoid printing messages on the
console unless they are errors or warnings. Genkernel should do the same
wrt its initramfs initialization code.
This has also the advantage of improving the boot speed.
scandelay=<secs> should be always preferred. Moreover, nowadays
automatically sleeping waiting for USB storage to come up in
the way we were used to do it doesn't work as one expects, because
USB is very common and USB storage devices are very likely to be
present on a system.
Furthermore, the initialization code after setup_slowusb is already
waiting for devices to come up.
While this makes out of the box booting a bit harder on some ancient CD/DVD
drives, it really speeds up the common use case by not sleeping for 3 seconds.
Our modprobe is an ancient heritage from the past, probably dating to
a time where busybox's modprobe features were limited. There is no reason
at all to keep using our own version instead of the busybox one.
This commit also makes modules_scan 15% faster.
The default value of ${ZPOOL_USAGE} is unset, quoting it would result into
a "" argument passed to zpool. The workaround to this is to use "dozfs=force"
boot argument.

Somewhere in the mists of time we lost part of the multipath patch, so
we were bundling the userspace, but not the kernel modules, or ever
using it.

Make ZFS only import the specified pool
Set zfsutil when mounting non-legacy rootfs
Check for /sbin/zpool in addition to /sbin/zfs
Print information messages when ZFS pools are imported
Prompt user when mounting a ZFS filesystem without ZFS support
Verify that <dataset> in real_root=ZFS=<dataset> is a filesystem
Dogfooding of the /usr mount code with the matching OpenRC change to
make the mounts RW revealed some bugs and gotchas in our prior code, now
fixed and verified to work.

instead. At the same time, mount cdrom into /mnt/cdrom instead of
/newroot/mnt/cdrom (which is now just a bind mount), this avoids
losetup to expose unavailable paths inside the live system, breaking
mkfs.btrfs (next upstream version, which does silly things with
/proc/mounts).
Set DO_slowusb as default, and make setup_slowusb unset it if it cannot find
a usb-storage attached. This makes genkernel ramdisk adhere to "noslowusb",
makes the ramdisk only wait if there is a usb-storage attached and should fix
gentoo bug #359619.
By adding the kernelcmd options "dokeymap" to MY_HWOPTS instead of
the HWOPTS version, "keymap" this typo broke the handling of keymaps
if you only had "keymap=<...>" in kernelcmd and did not specify "dokeymap"
too (which according to documentation should not be needed).
Only reason for this logic is to limit what entries in /proc/partitions
mdadm scans for arrays.
However this seems to break raids in containers (example Intel fakeraids)
as those containers are never scanned for arrays.
(On my system it activates /dev/md/imsm0, but never /dev/md/Gentoo_0 which
is the real RAID with the removed logic)
If someone has something dead-slow they do not want scanned for raids,
it is better if they specify their own mdadm.conf.
If someone finds an example of something that mdadm scans for arrays that
is not supposed to be scanned, we may handle that then.
This makes the ramdisk always mount some kind of /dev,
and then try to move it to the new root.
This unbreaks handling of nodes created pre-udev likefor example lvm does.
Change vgscan and vgchange so they are done in one go.
Faster since less work for the lvm command.
vgscan is still needed for some cases like dmcrypt where
/etc/lvm/cache is created, but not updated with the unlocked devices.
mdassemble can't handle newer metadata formats and fails for partitioned
arrays, among other things.
This...
- replaces the bundled mdassemble with proper support for mdadm
- fixes raid autodetection/assemble when no mdadm.conf is available
- fixes a compilation failure for newer mdadm versions
Tested w/ genkernel 3.4.10.907 and mdadm 3.1.3.
RAID0 btrfs volumes can be detected only if btrfsctl is started.
Since embedding extra executables in initramfs is already possible,
add minimal btrfs support inside linuxrc.
There were several places where a mixture of sdelay and "sleep 10"
were called without worrying too much, resulting in slower boot
time, mainly. This commit should fix the mess and make some order
in the slowusb saga.
