Also, have a look at sysvinit-2.74's ability to re-exec itself. Just say
telinit U and the new init loads up. This gives you the ability to eliminate
all references to your old libc (or your old init executable, when upgrading
init) before shutting down (and also makes the shutdown unnecessary if all
you are doing is upgrading init, since the new one will seamlessly take over
where the old one left off)
