I have but it doesn't give me /dev/null :-)

I am more concerned about older.

The thing is that a binary built on Redhat-7 works on 8, 9 and the
Fedora Cores (if those don't have their play-with-the-VM-map day).

By bumping it up you lose the ability to crosscompile for Rh-7 and its
derivates (RH enterprise Linux, whitebox) which are in wide use in
production environments.

Of course Redhat-7 had that "interesting" gcc-2.96 which I don't want
either so overall I'm happy with a RH-8 base.

RH9/FC1 (same thing) sucks for the crosscompiler because the linker is
dead slow.  Linking a big C++ library is several times slower than RH7
or FC2, last time I looked (not properly benchmarked).

I also bet 45 cookies that moving past RH-9 breaks things for other
distributions.

The current one works pretty well and doesn't seem to be a bad
compromise overall.

Then of course RH8 is among Linuxers known as the worst RH ever, so
what do I know?
