Quoting James Wilkinson <ubuntu at westexe.demon.co.uk>:
Slackware Linux has one big issue: consider a situation, when you are installing
a new package, which requires new version of library, say "GTK+ 3.0", for
example. You downloaded this library and installed it, overwriting "GTK+ 2.0"
on your computer. What shall you get after launching your favourite tool, that
is designed for "GTK+ 2.0"?
Second question: suppose that you installed OpenOffice 2.0 and hated it. What
additional packages you should remove after this package was wiped out? Are you
sure that your HD has no garbage and all installed software continue to work?
APT system was worked out as a solution of these problems and I like it. It
combines quick and dirty installation from binary packages with excellent
tuning when you are installing source packages.
There are many Linuxes that use another package management systems or don't use
them at all. You have a choice: simply change a distribution!
