Definitely. /etc should still work when mounted read-only.

I guess the 'old' scheme (SunOS, maybe old BSD) would be to use /etc,
/var/adm and similar paths, whereas the 'new' scheme (IIRC a bit SysV-ish)
uses a more thought-out method (/var/log, /var/run, configfiles in /etc or
/etc/<program_name>, /sbin for system binaries ...).

You might want to look at the Linux Filesystem Standard, which defines where
to put what. Conforming to fsstnd would make it a lot easier for people who
know a modern unix distribution to find things on a MiNT system.

If it helps, I can look up things on my Debian system.
