Would it be reasonable to default to gzip/gunzip instead of
compress/uncompress for the bootstap procedures? Ten years ago
compress was ubiquitous and gzip rare, but today I think that's
changing, probably because of patent issues on compress.
I've run into several Linux distributions which either have no
compress and uncompress (recent Mandrake) or have a kludge from
the sharutils package (SCO Group Linux 4.0 from UnitedLinux)
which uncompresses, but won't compress. This was easy enough to
deal with where it was entirely missing, but it took a fair
amount of time to figure out that /usr/bin/compress wasn't
working what with its error output buried in a uuencoded script.
I've done a minor hack on the openpkg.boot script from the
current openpkg-20030103.src.rpm which looks for a working
compress or gzip immediately, and quits with an appropriate
message if it can't find one.
Now if I can figure out how to build the bootstrap src.sh file, I
can test this thing :-).
