If we're about to start a Live image (i.e. if /dev/mapper/live-rw
exists) this script will take any files found in /updates (inside the
initramfs!) and and copy them into $NEWROOT.
This allows for hotfixes to be applied to existing Live images without
rebuilding the entire image.

Currently dmsquash-live-root requires that squashfs images be named
"squashfs.img" and all others be "ext3fs.img" or "rootfs.img".
If we've got a live image in initramfs, this patch will make dracut use
losetup and det_fs to determine the actual filesystem type of the image.

- use last ro/rw cmdline arg rather than favoring 'rw' over 'ro'
- don't bother with useless RES variable for holding $?
- only do fs check when $livedev is a block device

This patch adds a new option --force-add, which
can force dracut to load some module when -H
is specified.

fsck_single() operates directly on the device, so fstab is not
necessary. fs-lib functions make sure fscks don't complain.
Code is only commented out just in case I missed something.
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
Previously, '-a' was added for ext[234] filesystems if other
conflicting flag were not present. It's being done automatically
in fsck_drv_com() now (also for jfs and reiser).
The livenet module allows you to use a root arg like:
root=live:http://server.name/path/to/live.img ip=dhcp
The named live image will be downloaded with wget and then set up as the
root device.
It currently supports FTP, HTTP, and HTTPS. dracut will try to install
the CA bundle (/etc/ssl/certs/ca-bundle.crt) into the initramfs so that
SSL certificate checking will work properly.
If an HTTPS URL is given and the site fails the certificate check, the
file will be rejected and the system will not boot into it.

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*"
