If I understand correctly, the main reason for wanting a read-only root partition is that then we'd have a not-easily-corrupted partition for booting. Instead of moving most of /etc out of /etc, how about approaching the "problem" by trying to pick the set of files that are needed for booting before mounting /usr. Move a few files out of /etc into /sbin or wherever (first few lines of /etc/rc, network initialization for diskless systems, a file that tells where to fsck&mount /usr from). (/setc? Yecch.) Most of /etc could then be left as it is, except it would live in /usr (or /var?). /etc would be a symlink to /usr/etc. Booting would look like: mount / run /sbin/mother-of-all-rc's -- which does the rest: run ccdconfig fsck /usr mount /usr run /etc/rc (which is like now except it doesn't run fsck.) ++sja
