So I am currently patching /etc/rc to remount ro which I accept is special territory. I like ro partitions not only for the lack of need to fsck and faster boot for systems that have had thee power pulled.
It would be a lot nicer to be able to mount -uw / in rc.shutdown. Whilst likely not a major issue. I also started to wonder whilst reading man rc.shutdown, if a daemon or other process could potentially use /dev/urandom between saving the seed and shutdown so could/should the random.seed be saved a little later after /etc/rc.shutdown runs? -- KISSIS - Keep It Simple So It's Securable
