In what way is BLAG poorly done? It is lagging behind Fedora releases, yes -
but only because it is a lot of work on few people. You are welcome to join
if you'd like to make it more proper:-)
Also, gNewSense is more or less in sync with debian squeeze if you
debootstrap the latest version "parkes". Installed it last week, and it is
quite nice - the 64-bit repo seems unstable, but i386 (and probably mipsel)
works fine.
The new Dynebolic will be on one of my machines as soon as it becomes
installable, but I also recommend testing Musix 3 - it is beta with a bug or
two at the moment, but will be great when released.
Of the above, I mainly use BLAG and Trisquel - but all the free distros I
tried have some excellent features of their own that shouldn't be missed.
