LXC on Ubuntu 11.10 Looks Good

December 25th, 2011

I upgraded my Lenovo g555 laptop to Ubuntu Oneric Ocelot on Friday and it was a little rocky, but now its working really well.

I have setup a few new / different items:

  • I'm using the ATI proprietary driver, much to my chagrin solely because it gets less hot than the open source one. As far as performance goes, I don't notice a difference, but no doubt - KMS is awesome. The raw terminals look magnificient. Specifically, using this makes all the difference:
 amdconfig --px-igpu 
  • I am now using ext4 for the /home directory. I was hesitant to use ext4 because ext3 is so reliable, but then I read about some basic performance factors - like extents specifically, so I'm giving it a go.
  • While I'm using OpenVZ extensively these days, I'm now checking out LXC for a development environment on my laptop. I actually just setup another user account "app" that I ssh into (yes, ssh'ing to the same machine - for ssh forwarding), and that's working OK because I've got Ruby installed with rbenv, but I want to encapsulate mysql, and I don't want it polluting my base workstation OS.
  • I'm also using libnss-extrausers because it is awesome - I'd rather use something like puppet or csync2 to manage hard files instead of using ldap
    • maybe even something like git-annex for that, or maybe just plain git.

I'm still doing plenty the same:

  • Gnome + Awesome
  • Still using rbenv, homesick, and major dotfiles in my home directories (which is why I split my laptop user with the development user)
  • Still using jEdit, sorta.

I'm no longer using:

  • Picasa3 - see ya! I'm tired of Wine, and realized I can manage my images better than Picasa can.
  • No longer bothering with the default folders in my home

Other stuff catching my attention:

  • Fuse BindFS
  • mbr
  • mr (not related)
  • caspar ( see this)

Probably going to stick with csync2, maybe? Actually I'm liking the idea of simply using git more and more. There are actually plenty of folks doing this, and here's the best example I found:
