So far, my only issue has been that the system doesn't want to boot without the
password, not good for a server when the protected filesystem isn't needed to
run (such as source or docs, contact info, etc). I attempted to "solve" this by
using "noauto,user" so I could hand mount it, or putting it into automount,
neither of which worked properly with fc11 where I tried it first.
