Never really used Gentoo, so can't say... =)  But unnecessary
recompiling seems a little silly to me.

You're right... passing init= is probably easier.

Poking in my subversion rep here, I see I made a patch to workaround
that so I guess it doesn't work "out of the box".  It's the runlevel
issue that's the culprit.

The patch is here:

http://svn.annvix.org/cgi-bin/viewcvs.cgi/releases/1.2-CURRENT/SysVinit/SOURCES/sysvinit-2.85-avx-silent_no_runlevel.patch?root=packages&rev=4797&view=log

The problem is in halt.c it looks to see what runlevel you're in and if
you're *not* in runlevel 0 or 6, it'll do the reboot stuff.  Obviously
with runlevel reporting:

[vdanen@build ~]$ /sbin/runlevel 
unknown

it doesn't let you do much.  I just patched it to remove the checks for
the runlevel and it does work here.  Not sure how easy it is to put your
own custom patches into Gentoo tho.
