Basically, yes - but as I understand it, somebody's alrady dealt with
the problems and got a cfs working with compression support for gzip,
compress, pkzip, lha, arj and rar...

True - I never thought of that...

Not necessarily...
The obvious way to deal with updating a file in an archive would be to
read the relevant file out from the middle of the archive and build
the new version on the end, then when the file is closed, cut the old
file out from the middle. This is a fairly trivial task where tar is
the outer layer, but considerably more complex when there's a gzip
wrapped round it...
Best wishes from Riley.
