The great thing about Slackware is Pat Volkerding doesn't customise any of the software, whereas distro's like Fedora heavily modify the kernel for example Pat doesn't, I feel slackware is really what Linux is about a collection of software and utilities made by different people put together to make one system.
However that also means there are no distro specific config utilities, all system configuration needs to be done by editing text files and working on the terminal. If your looking for a replacement for Windows then look elsewhere.
I currently use Slackware on my server, but that installation is starting to get out of date, I'll not be updating Slackware but moving onto FreeBSD, however if I was to carry on using Linux then only Slackware will do |
