From rc.sysinit on my RHEL3 box, it looks like you can create
/etc/sysconfig/autofsck. There is an AUTOFSCK_DEF_CHECK that can be set to
yes to force the check and PROMPT can be set to no to skip the prompt.

All of this only happens when /.autofsck exists on the filesystem.
/etc/init.d/halt removes this file when shut down properly.
