Improvements to install.sh ?

[Michael H. Warfield]

Hey Juian!

	Wow...  Serendipity or what.  I was just in the middle of a yum upgrade
of some Fedora 8 systems to Fedora 9 and ran smack into a bloody
nightmare with MailScanner.  The problem here is that Fedora 8 had perl
5.8 and had all the modules installed for that.  Fedora 9 has perl 5.10.
The yum upgrade (which was also nightmarish due to the signing key
rollover and a dependency hell on openssl and openldap) upgraded all the
base perl stuff but not the MailScanner stuff.  Trying to reinstall
MailScanner seems to work but then it doesn't run, complaining about
Hostname/Long.pm not existing amongst others (fix one and there's more).
The problem is, the rpm is installed but for the wrong version of perl
and wasn't upgraded and the install doesn't install it because it thinks
it's already there, even though the .pm module is in the wrong version
directory.  I had to manually build and install the bad modules until
MailScanner would restart.

	I strongly suspect that this would be the case even if I did not use a
live yum upgrade but used an anaconda install (CD or preupgrade) as
well.

	My suggestion for install.sh would be a sanity check to insure the
correct rpm's are there for that distribution or a "reinstall" option
that will reinstall the rpm's even if the exact same rpm is already
present.  Yeah, this is a corner case that rarely comes up but it's an
UGLY corner case, in this case.

	Mike
