Not tried it - I'm more or less wedded to Debian right now though (but 
really only because I have a couple of dozen physical servers all running 
Debian - if only there were 25 hours in a day ;-)

I found the stock shutdown (in Debian, anyway) rendered the host with a 
read-only root partition rather than shut down... The 'lxc' script I'm 
using attempts to 'fix' inittab and some of the rc scripts though, but 
file-rc gives me better control.

file-rc still has /etc/init.d but no /etc/rc.x directories. Instead 
/etc/init.d/rcS is a big script that parses /etc/runlevel.conf - and that 
file kicks off scripts as needed.

e.g. /etc/runlevel.conf contains lines like:

# <sort> <off-> <on-levels>     <command>
02      -       S               /etc/init.d/hostname.sh
#06     -       S               /etc/init.d/keyboard-setup
#11     -       2,3,4,5         /etc/init.d/klogd
#12     -       2,3,4,5         /etc/init.d/acpid
12      -       S               /etc/init.d/mtab.sh
16      -       2,3,4,5         /etc/init.d/ssh
19     -       2,3,4,5         /etc/init.d/mysql
21     0,1,6   -               /etc/init.d/mysql

etc. The default runlevel in Debian is 2.
