This commit allows the waiting for a device to be cancelled.
When the resume partition does not exist, it becomes quite hard
to work out what to do (you have to either create the
/dev/resume symlink manually, or remove the 'finished' job
that is waiting for it). Additionally dracut incorrectly
displays a message about not being able to find the root
device, which is bogus and misleading.
This commit should just bail on the whole resume thing
if the device cannot be found and proceed with a normal boot.
inst_mount_hook <mountpoint> <prio> <name> <script>
Install a mount hook with priority <prio>,
which executes <script> as soon as <mountpoint> is mounted.
add_mount_point <dev> <mountpoint> <filesystem> <fsopts>
Mount <dev> on <mountpoint> with <filesystem> and <fsopts>
and call any mount hooks, as soon, as it is mounted

[harald@redhat.com: usable_root(): relaxed check for root]
The "read" shell builtin consumes backslashes, which is a problem if
your root device is something like "LABEL=Fedora\x2016".
Using "read -r" tells the shell to leave backslashes alone.
Whitespace removal in:
out="${out}${chop# }$r"
will damage certain strings, for example the following call:
str_replace ' aax aaxaa' x y
would return 'aayaayaa' instead of ' aay aayaa'.

To not pollute dracut-lib.sh, all the fsck related functions were moved
to fs-lib.sh. The functions available are as follows:
- fsck_single
this will detect/verify filesystem, check if it has necessary tools and
check the filesystem respecting additional flags (if any), using
specific "driver" (or falling back to generic one). Currently
available: fsck_drv_{com,xfs,std}. 'com' is used for tools following
typical subset of options/return codes (e.g. ext, jfs), 'std' is used
for "unknown" fs and doesn't assume it can be run non-interactively.
Please see comments around the code for more info.
- fsck_batch
this will check provided list of the devices;
Both of the above functions will fake empty fstab, to make generic fsck
not complain too much (excact devices are always provided on the command
line).
"Known" filesystems currently: ext234, reiser, jfs, xfs
- det_fs
Small bug fixed - as this function is meant to be called in $(), it may
not be verbose.
Current behaviour is:
- if detection is successful, use its result
- if detection is not successful, and filesystem is provided, return
the provided one; otherwise use auto
if a value of a key on the kernel command line includes wildcards, these
would be expanded.
E.g., if you have "key=/dev/sd*" the value would be substituted with
"/dev/sda /dev/sda1 /dev/sda2" instead of returning "/dev/sd*"
Both functions will be used by rootfs-block and fstab-sys modules.
Both are based on code present in mount-root.sh, though few changes are
present.
det_fs:
will try to determine filesystem type for supplied device, even if it's
not auto. If fs cannot be detected, or if the detected one differs from
the supplied one - a warning is issued (so user can fix its stuff later)
wrap_fsck:
will call fsck for specific device with optionally additional
fsckoptions. The function returns fsck return value.
