Synopsis

Mark Krenz will be giving a presentation on Gentoo Linux. Gentoo has been a popular distribution in recent years for Linux vetrans. It allows you to almost completely customize your programs to your desires with simple package management commands.

This will be a good overview of what makes Gentoo stand out from the rest of the Linux crowd and also shows what people like so much about FreeBSD and others. Hopefully this presentation will show you that despite what you may have heard, installing and using Gentoo isn't terribly painful.

Post meeting summary

We had a better turnout for this meeting and two new people who were Gentoo users, but wanted to learn more.

Mark installed Gentoo Linux stage 3 in just under 2 hours!! He also demonstrated LVM partitioning, reiserfs and explained many things along the way.

Things mentioned during the presentation

This list is here so people who attended the presentation can remember something that was covered. Its probably not complete.


  • USE flags in /etc/make.conf and on the command line.
  • ACCEPT_KEYWORDS="~x86" for beta packages
  • /usr/portage/profiles/use.desc
  • OVERLAY="/usr/local/portage" - Portage overlays for setting up your own custom pacakges
  • emerge -pv packagename
  • -j2 (Option passed to make to increase parallelization on multi processor systems. Add 1 to the number of processor cores you have. This is not Gentoo specific)


  • LVM (Logical Volume Management)
  • reiserfs - Faster filesystem that works well with LVM. Also check out jfs.
  • screen (program for multiplexing your terminal)
  • TCP congestion notification option in kernel [1] (this is kinda old though, they might have fixed the problem with this)
