. detect both formats in /etc/rc . generate new format in setup . obsoletes /etc/fstab.local: everything can go in /etc/fstab . put shutdown/reboot/halt and a copy of /usr/adm/wtmp (/etc/wtmp) on root FS so that we can do shutdown checks before mounting /usr . new fstab format makes getfsent() and friends work

(3) Exit setup and shrink a partition using a different OS
