Yes I agree to point, some package managers are intelligent enough to
know about no-deps, and it means that, last time I checked apt has no
clue about it, I recall the fun I had removing the deb postfix, easy on
RHEL though, but even simpler with Slackware (given its not installed
lol)

Sometimes their attempts are not good enough, I use ubuntu  LTS for the
LTS purpose, else I'd go back to RH for it, and apt is a PITA, it almost
wants to insist on being the be all and end all, ala MS *sigh* but to
elaborate puts us further off topic here....
But back on topic, last LTS version of ubuntu didnt understand RR SPF,
it was a  nightmare removing the old version to install source, it
wanted to remove half the blasted system, so I gave up and just
installed  source version over top of the installed binaries, when I dud
LTS upgrade from 8.04 to 10.04, it had no problem updating, but I didnt
like the old version still in use so once again installed source over
top :)

Heh its nice to see 5.5 of MySQL no longer requires
adding /usr/local/lib/mysql to ld.so.conf, it puts it in the right lib
dir with identical config (well converted to CMake anyway, and don't get
me started on that).
Oh MySQL, thats another thing that's way out of date on some of these so
called "modern" distros.

Yep, its why on servers I use Slackware, I used to be a real RH fan, but
as you pointed out, too many "gotchyas" when needing modern packages.
Slackware makes it simple, never had a server upgrade fail through
dependency hell :)

I used to build gnome, now _that's_ pain for you :D  Just dont have the
time, nor patience for that these days (sign of old age I guess)..  So I
let desktop distros do it for me hehe.


and I think we've taken this so far off topic now, my apologies to the
list mums/dads
