Changes to init scripts to better support stateless:
--rc.sysinit--
- don't update mtab in a r/o root
- mount on sys and /dev/pts returns EBUSY on a readonly root
- [ -n $CLIENTSTATE ] is always returning true, causing an unnecessary timeout
--network--
- /etc/mtab may not have any mount information in the readonly-root
cause, but the root mount is likely to be a network mount. Without
this, nfs hangs the reboot process.
--halt--
- don't try and update a read-only mtab
--rwtab--
- /var/empty/sshd/etc/localtime needs to be overwritten by sshd at
startup
- /var/lib/random-seed is written to at shutdown; this fixes the
error but doesn't return the functionality lost in a r/o /var/lib.
