Uhm, AFAIK you don't need to reboot at all, a restart will do fine. When you 
quit a program, nsswitch will dlclose() all libnss_*.so, and dlopen() them on 
startup. So, if you have changed them inbetween, on restart the new version 
WILL be used.

The same goes for /sbin/login: when you log out of a session on a VT, a 
new /sbin/login is started. There really is no need for a restart, unless you 
use nscd, which you shouldn't anyway: it's much more trouble than it's worth.
