With System V, shutdown -s would take you to single user mode,
not do a reboot at all.
To go to single user from multiuser, I use
telinit 1
takes me to single user with whatever runstate one is in. This kills
most everything. See /etc/rc1.d, /etc/init.d/README. It does leave
file systems mounted, so if you need to do things to the file systems,
(fsck and such) you will need to umount filesystem, or remount ro
filesystem:
umount device-for-filesystem
mount -n -o remount,ro /
The mount command wants to write fstab, whether remounting ro or
remounting rw. The -n allows you to actually remount the filesystem
without writing on fstab. I missed this myself, and had problems until
it was kindly pointed out to me.
I have not used it, but telinit 2 should take you back to
multiuser.
