If new modules are introduced, or modules get renamed, or modules change
from builtin to real modules, we want to include them in the host-only
image, just to be safe.
An exception is multipath devices, child and top layer device may have
same uuid. As dm devices maintain /dev/mapper/* as persistent names,
just do not doing converting for them.
No automatic assembly is done anymore by default. You will have to
specify exactly what devices to assemble
("rd.md.uuid=" "rd.luks.uuid" ...)
or use "rd.auto=1" or "rd.auto" on the kernel command line.
For big servers with thousands of disks we don't want to assemble
everything by default (error prone, slow).
"inst busybox" no longer seems to work when busybox is at
/sbin/busybox. Reproduced on Fedora 18 (dracut-023-39.git20120910).
Use type -P to find the full path to busybox to solve this problem.
For devices with filesystem, udev /dev/disk/by-uuid/* links are always
reliable. So improve the get_persistent_dev() by using by-uuid/* firstly,
and fallback to use by-id/*

ismounted handles both find-by-dev and find-by-mnt, but there's two issues:
1. for find-by-dev, it use readlink to get the canonical dev name, but
lvm is different with other devices, the canonical name for lvm devices
are symlinks like /dev/mapper/vg-lv00
2. for nfs mounting, just use [ -b $dev ] is not enough, it need being handled
seperately.
Per Karel Zak's suggestion, findmnt util is suitable for this purpose, it
handles these cases well, so just use findmnt instead of implement all the
logic by ourselves. Thanks, Karel.

kdump module also need to convert dev name to udev symlinks.
So better to move function get_persistent_dev() to dracut-functions.sh
Also in this patch improvement and fix the original function:
a) use udevadm info --query=name to get the kernel name.
This will fix the issue caused by passing symbolic link of a device.
b) fix a bug to compare $_tmp instead of $i with $_dev. Really sorry,
should have tested more carefully.

/run will get mounted at $NEWROOT/run after switch_root, but it's not
there yet. bind-mount it in place so updates for /run actually land in
/run.
(also: remove a redundant check for existing directories. mkdir -p
doesn't do anything if the directory already exists.)
When emergency_shell() happens, it does 'setsid --help' to figure out if
the setsid binary supports the '-c' flag (to set the controlling tty).
This output shows up in the logs (and on-screen if you're using
rd.debug), which keeps confusing people looking for other problems.
Using "case" instead of "strstr" lets us avoid this.
It looks like ip=ibft has been busted since
25aa3c5 network: refactor stuff from netroot/parse-ip-opts to net-lib
which moved ibft parsing code out to the ibft_to_cmdline function.
The use of ifname_mac was partially replaced by a local mac, but not
completely, causing ibft_to_cmdline to abort without generating network
configuration options.
