If /sbin/init is an absolute symlink (e.g. to /bin/systemd) the
readlink check doesn't work as $rootmnt is involved.
The validate_init() shell function takes care of this fact, as
well as when guessing the init binary points to a directory. For
example Ubuntu's upstart has its configuration inside /etc/init
whereas this is considered a valid run_init_process() binary by
the Linux kernel and `test -x' returns true when checking for
executables.
Therefore be more conservative with providing full backwards
compability as well as new added support for absolute symlinks at
the same time.
Closes: #590744

MODULES=dep fails when / is ubifs. This patch adds support for
something like root=ubi0:rootfs when ubi is modular.
Quoting Martin:
It essentially does three things:
- adds the correct modules to the ramdisk (for MODULES=dep and MODULES=most)
- reads ubi.mtd= from the command line
- loads ubi with the ubi.mtd info and ignores the "Waiting for root" check
I've successfully tested this with a kernel with modular ubi and with
the following boot variants:
console=ttyS0,115200 ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs
console=ttyS0,115200 ubi.mtd=2 root=ubi0_0 rootfstype=ubifs
With
console=ttyS0,115200 ubi.mtd=2 root=/dev/ubi0_0 rootfstype=ubifs
I get an error that it cannot mount root but I suspect this is an
ubifs error and has nothing to do with i-t (since at this point I can
manually mount it with -t ubifs ubi0_0 whereas the /dev/ variant
doesn't work).
Tested with MODULES=dep and MODULES=most as well as with a kernel that
has ubifs built in.
Closes: #582858

Older kernel versions (like the one shipped with Lenny) don't
support devtmpfs. Therefore display a warning message when
falling back to tmpfs. See #501359.

as mentioned by Christoph Bussenius in #535008, it does appear that
setting BOOTIF from the value in /proc/cmdline is needed. at the time
i wrote the patch, i'm not sure it was, but it definitely is now.
with these patchese applied, it seems to work. at least for the moment.

make it more concise:
* use POSIX ${parameter:+word}
* replace *[/]*) by just */*)
* test exit code of command -v rather then running test -x on it
while we are at it fix another command -v usage in scripts/functions.

while at it cleanup the variable name that came due to legacy
naming nfsopts in a very early initramfs-tools release.
"The local-top/iscsi initramfs integration script uses the
configure_networking function, which depends on the IPOPTS environmental
variable set by the init script. However, this variable is not
available, because it's not exported from init, and local-top/iscsi is
not sourced but executed. Thus static IP configuration on the kernel
command line is not communicated to the script."

As there is no /dev/disk/by-label//, we need to follow udev

The cmdline parameter `break=init' failed to work. It looks like the variable
`break' is unset before `maybe_break init' is evaluated.

with bad luck that might still be on hda1,

no need to check if the string of the corresponding variable exists,
just unset all of them, but 2 that we need to pass on for calling init.

This reverts commit 74be87d35841eae3c3febf00b568df5232c85f06.
talked to hpa and he seemed quite unconvinced about that report.
the run-init code doesn't also seem to backup that claim.
so nuke it for now until better analysis shows up.

grave bug as makes a Debian slug unbootable.
Thanks Kevin Price <kp@kevin-price.de> for report and
Martin Michlmayr <tbm@cyrius.com> for debugging.
The cause was the reordering of the ROOT export *after*
it had been sourced in init. Fix it by allowing all
exported variables to be ovverriden aka hardcoded.

long outstanding bug.
[ note: seems fixed in fedora mkinitrd, but not in opensuse.
they simply call run-init like anyone else. -maks]

If you have quiet in your /proc/cmdline you can never
reach any debug bootoption anymore.

You’ll notice a strange error message due to an empty
$init if the rootfs can’t be found.

Fixes bootfailure on bogus init bootarg too.
Plus there may be a rootfs without init, but with sh.
