Well, the system I'm imagining would almost certainly have to run from the
root partition - it might well even have to be kernel resident.  So it would
still be there.

There could be a case for listing a set of system-essential files which are
always kept as text in a real /etc.  But plenty of config files are *not*
potentially fatal - httpd.conf, sendmail.cf, exim.conf..

True.  And we should be cautious about such a system.  But just because
someone else has done an idea badly, it doesn't mean it isn't a good idea.

Back-ending onto some RDBMS makes it *much* simpler to move defaults between
machines - which is a priority for a certain kind of user...

Mind you, it looks like we're going the linuxconf route, so I'm just keeping
this thread alive out of interest.
