There shouldn't be a problem if you install and run GENERIC on one machine and 
then transplant that machine's hard-drive to another machine.

/etc/rc.conf is one area to beware of, another would be ipfw/ipf having rules 
based on interfaces.  Something tells me you'll want to have a copy of 
/etc/fstab available, but I can't for the life of me think why.
