Found this bug in Genkernel, might help you...

[gixer]

Today I used Genkernel 3.4.10_pre2 to regen a kernel for me (yes I am lazy ). Upon rebooting I got this:

/etc/initrd.scripts: 936: Syntax Error: Bad Substitution

Kernel Panic - not syncing: Attemtped to kill init!

and that was it, system froze.

After some investigation, this is what I did to fix it.

nano -w /usr/share/genkernel/generic/initrd.scripts

goto the very last lines:

find_looptype() {
LOOPTYPE="${LOOP##*.}"
[ "${LOOPTYPE}" == "loop" ] && LOOPTYPE="normal"
[ "${LOOP}" == "/zisofs" ] && LOOPTYPE="${LOOP:1}"
[ -z "${LOOPTYPE}" ] && LOOPTYPE="noloop"
}

the line it's complaining about is:

[ "${LOOP}" == "/zisofs" ] && LOOPTYPE="${LOOP:1}"

take out the ":1" so it looks like so:

[ "${LOOP}" == "/zisofs" ] && LOOPTYPE="${LOOP}"

I'm assuming because the init uses ash instead of bash, ash handles substitutions differently, I ran this script in bash with the -n flag (keeps it from actually running the script and simply syntax checks it) and got no complaints. I don't do shell programming, maybe someone else can comment on why, or even better what the correct solution should be. All I know is this resolved it for me, and I've had no ill side-effects.

Now re-run genkernel, and poof, no more error, it boots correctly. I hope this saves someone else a few hours of research or even worse keeps them from not being able to use their machine. Thank goodness I keep several revisions of kernel on my /boot partition, and was able to simply revert, figure out the problem, and now I'm running the newest kernel.

Hope this helps someone.

Did you report it to genkernel maintainers?
