[Ltsp-discuss] patches to allow multiple display managers, font servers

[Andy Rabagliati]

Folks,

  I use a central booting manager, with multiple application
  servers for load balancing and redundancy.

  I previously posted patches to ltsp3 to handle this, here are
  patches for ltsp4.1 to do the same thing.

  These patches hopefully are backwards-compatible, meaning that
  there should be no ill effects on implementation.

  lts.conf can now contain multiple space-separated values for
  XDM_SERVER and XFS_SERVER

Cheers,   Andy!
