It works but it might stop in the middle of the apt-get upgrade on the 
sysv-rc package if you removed by hand some init scripts on the guest, 
you will need to do an apt-get -f install then an apt-get dist-upgrade 
again afterwise and it will be OK.

Don't forget to re-remove the un-needed init scripts from /etc/rc.*/.
Here is the code i use for that matter (i have mksh, Perl and GNU 
Parallel on all my guests installs but it should work the same with 
ksh93 or bash and xargs instead of parallel) :
         vserver ${VSERVERNAME} exec /bin/mksh -c "ls -U 
/etc/init.d/*@(check|udev|hostname|mtab|mount|fs|reboot|random|hwclock)* 
|perl -pe 's#^.*init.d/(.*)\$#\1#' |parallel 'update-rc.d -f {} remove'"
