Hi Community!

recently Enrico and I had a discussion (not the first)
about the future of linux-vserver, and what path to
choose for 2.6 ...

the options seem to be:

 a) freeze the 2.4 vserver development at some
    point, only do some updating and maintenance,
    and continue with a SE-Linux/LSM version of
     - smaller, less intrusive, linux-vserver
       patches for 2.6.x
     - additional security features provided by
     - userspace configuration of vservers would
       require extensive changes (unification,
       procfs security, ...)
     - different setup/tools between 2.4 and 2.6

 b) extend the current 2.4 and 2.6 solution in
    parallel, providing all new features for both
    branches, independant of kernel version.
     - same tools for 2.4 and 2.6, easy migration
       between 2.4 and 2.6 (and back if desired)
     - same features, no 2.6 only features.
     - more intrusive vserver patches for 2.6
     - some features might collide with LSM stuff
     - probably slower development for 2.6
 c) add an additional SE-Linux branch and keep
    the existing 2.4/2.6 solutions in sync
     - easy migration on the non-SE-linux branch
     - similar features in 2.4/2.6/2.6SE.

     - definitely slower development for both
       2.4 and 2.6 branch ...

I would like to get your opinion on that, especially
regarding the following questions:

  1) should the 2.4 branch be frozen, and if when?
  2) is it bad if 2.4 and 2.6 branches diverge?
  3) is multitude (2.4/2.6/2.6SE) preferred over
     development speed?
  4) is a 2.4/2.6 migration path important to you?
  5) what branch 2.4, 2.6 or 2.6SE would you prefer?
  6) what branch/version do you currently use/test?
