I think this error is more confusing to most people than it needs to be,
and it's not really accurate any longer. Generalize the message and
inform the user that we simply couldn't find the root device.

These are all root owned, so we don't need to be concerned about DoS

This is mainly for avoid this:
[ramfs /]# mount /dev/md0 /mnt/a
[ramfs /]# mount -o bind /mnt/a /mnt/b
[ramfs /]# mount -o bind,remount,ro /mnt/b
warning: can't open /etc/fstab: No such file or directory

This feature was present in archiso_pxe_nbd for a long time.
it avoids to configure more than one device (if present) by ipconfig
with the same parameters.

* ipconfig cmd writes a file in /tmp that is ready for direct evaluation.
We can use this instead of parsing the output, to do this some variable
renames are needed.
* Add /tmp as part of "base" layout since this can be used by others hooks/cmds.

This is a much better solution than busybox's, as it will move our API

Do variable name validation via the case labels rather than via PEs.
This frees up the fallthrough case to simply ignore things we don't
understand (and not exist).

Provides /sbin/fsck and any helper binaries to the image. If processed
after the autodetect hook, only the helper for the root FS is added.

This adds support for fsck'ing root at bootstrap if the fsck binary and

Rather than immediately defaulting to /dev/root, attempt to resolve the
major/minor pair back to a block device. If we can't do this properly,
then fallback to /dev/root.

This allows a caller to pass in a device by name and get a /dev node
returned. Note that this is heavily limited in that only the root device
can be identified by major:minor.
This might break init's API, if such a thing exists.

Providing this means we no longer need blkid for FS detection, as mount
will do this for us. Adds a slight bloat to the image, in exchange for a
huge convenience. Messaging is changed to assume that /bin/mount will
provide useful feedback for us on failure.

- Always call this function. At worst, just return the current kver.
- Do all our error reporting from within the function.
- Add an additional check for existance prior to allow for a more
appropriate error message when we encounter a situation such as /boot
not being mounted.

cc36db45 was a bit too strict about localizing variables and blew out
TMPDIR, which might be a legit variable sourced from the calling
environment. Restore this behavior with a bit of refactoring, and
additionally add in a check to make sure the temporary directory is
writeable before proceeding.

As it turns out, the mountpoint toy from util-linux isn't really at
feature parity with sysvinit's. In particular, and with respect to
v2.20:
- It throws false negatives when /proc isn't mounted. Rather, it should
fall back on using stat(2), as is the basis for sysvinit's tool.
- when /proc is mounted with as source of 'none', it segfaults on a null
dereference.
Patches have been sent upstream to resolve these issues, but in the
meantime, we're mounting /dev and /proc for very specific reasons.
Instead of relying on a fork/exec to figure out if these API FS's are
mounted, use a simple bash test to see if these specific needs are
available within the FS.
One of many possible fixes for FS#26344.

If we encounter a BOOT_IMAGE var taken from grub2, the first character
could be a '(' which will throw off busybox's parser and error out.
Reverse the comparison so that the LHS is always a constant, which can
be compared to anything (including nothing at all).
