Well, I have Fedora, Debian, Ubuntu, CentOS and Slackware Workstations and Servers to mantain.
While I have to fight against meaningless and mad configurations (Who said "Debian Style"?!?) on most of them with Slackware I can really know where things are and what they do.
A pratical example: I found different bug in the Package Management Systems and I found myself in the trouble to resolve dependences that was not resolved by RPMs Package System or apt-messy-tools and... (surprise!) files were not where they meant to be! O.o
I mean... If a package developer decided to put config files in /etc why the hell you have to change this?
Just look at /etc/rc.d/rc.4 in Slackware.
Go to second attempt to find gdm!
And find the comment: " Someone thought that gdm looked prettier in /usr/sbin, so look there, too"
And WHO the hell put it there?
