The system should complete booting. Start an SSH session as root to the new system.
Even though it has seven read-write minidisks, it should be configured with most of the
directories linked read-only. You may choose to verify that certain disks are read-only while
others are read-write. Try the following commands:
# touch /etc/foo
# touch /var/foo
# touch /root/foo
# touch /srv/foo
# touch /tmp/foo
# touch /foo
touch: cannot touch `/foo': Read-only file system
# touch /opt/foo
touch: cannot touch `/opt/foo': Read-only file system
# touch /usr/foo
touch: cannot touch `/usr/foo': Read-only file system
