You can copy static /dev - no problem. When udev starts it will just
mount its own stuff over the static /dev. You do actually always need
some files to boot: at least /dev/null and often also
/dev/{tty*,console} and possibly others (depends on your init system).
Anyway: copying /dev is a good idea.Bye, Daniel -- PGP key @ http://pgpkeys.pca.dfn.de/pks/lookup?search=0xBB9D4887&op=get # gpg --recv-keys --keyserver hkp://subkeys.pgp.net 0xBB9D4887
