I have been using Linux for quite a while. Previously, I compiled my own kernels (in Slackware) and on a professional level have worked with both Slackware, RedHat and SUSE.
Fedora for basic installs. Gentoo and LFS for fun.
At least 10 years.
I've been using Linux off and on since the early 1990's (starting with an install of Yggdrasil). Currently, I am working on SAP on HP-UX installations but I'm hoping these are migrated to RedHat soon!
