The `/lib/udev/vdev_id` helper is superceding the `/lib/udev/zpool_id` helper,
which is deprecated and will be soon removed upstream. zfsonlinux/zfs#1183
Add a new `/etc/default/zfs` option:
* `ZFS_INITRD_PRE_MOUNTROOT_SLEEP`, which wastes an arbitrary amount
of time in the initrd environment before wait_for_udev is called.
This option is primarily a kludge for bad mpt2sas hardware that can go dumb
during system initialization. Thirty seconds should be enough for most
affected computers, but five minutes might be required in the worst case.

When `update-grub` is invoked, `os-prober` tries to mount each zvol
node, which is slow on systems with more than a few hundred volumes.
Add a device test for `os-prober` that returns early on zvols.

The `zfs set mountpoint=/ "$ZFS_BOOTFS"` command in the initramfs
script had a typo that made it a noop.
This command ensures that the root filesystem has a sensible mountpoint
property. The error wasn't noticed because most of the Solaris userland
goodies for ZFS aren't yet implmented for Linux.
Closes: dajhorn/pkg-zfs#41
Always hook the udev rules that read the `/etc/zfs/zdev.conf` file into the
initrd, even if the system is not using the zfs-initramfs package.
This change ensures that `/dev/disk/zpool` device aliases are ready in time for
`mount` calls early in the init stack.

Subject: Re: [zfs-discuss] Re: Unable to open /dev/zfs: Permission denied.
Rather than allow all ZFS commands to be executed without a password with
sudo, I limit passwordless use to read-only commands with the following in
my /etc/sudoers file. I have less fear of accidentally doing something
willy nilly.
The `zdb` utility requires pthreads for some functions, but the
necessary library is not automatically added to the initrd because
it is not detected as a dependency.
Closes: dajhorn/pkg-zfs#26
If the root pool contains a zvol, then udev tries /sbin/blkid and
emits a warning, which is usually invisible because it happens
after GRUB changes the console mode for Plymouth.
Adding /sbin/blkid to the initramfs manifest satisfies the udev
warning and results in a small boot time improvement.
The zfs-initramfs package directly depends on the zfsutils package,
so utilities in the COPY_EXEC_LIST should always be available.
Unlike some other initramfs hooks, we aren't currently detecting
whether anything in /sbin is actually necessary to start the system,
and the earlier behavior obscured a packaging mistake.
Ubuntu Natty and Ubuntu Oneiric systems seem sensitive to a missing
or stale /etc/zfs/zpool.cache file. The only circumstance where
these systems reliably import the root pool is when the cache is
current and all pools are automatically imported at module insertion.
Good behavior on earlier Ubuntu releases could have been accidental.
Consider inhibiting automatic zpool imports in the initramfs
environment and doing a full import in the regular system instead.
Promote the utilities and libraries from /usr so that they are
installed to the root filesystem, and move the udev helpers
from /usr/bin to /lib/udev.
This reflects a similar change in the upstream RPM packaging.
Revert to mounting the root filesytem like this:
mount -t zfs -o zfsutil "$ZFS_BOOTFS" "$rootmnt"
Ideally, the root filesystem would be mounted like this:
zpool import -R "$rootmnt" -N "$ZFS_RPOOL"
zfs mount -o mountpoint=/ "$ZFS_BOOTFS"
but the MOUNTPOINT prefix is preserved on descendent filesystems after the
pivot into the regular root, which later breaks things like `zfs mount -a` and
the /etc/mtab refresh.
Assuming one filesystem on the pivot and implicitly remapping it is sensible
behavior for the exec init. Keeping the -R prefix is similarly sensible
behavior for the zfs utility. Thus, the initramfs is probably the best place
to do something unusual.
The pre-init script in the initramfs environment sets the hostname
if the regular /bin/hostname binary and the /etc/hostname file are
included by the hook.
The pre-init invokes `/bin/hostname -b -F /etc/hostname`, which is
incompatible with the busybox builtin because it lacks the '-b'
switch.
This commit mysteriously resolves the console corruption that
occasionally happens on systems that boot into a native ZFS root
filesystem.
