  vserver 0.5
  Change log

  The new vserver package relies on new ability found in the kernel
  patch ftp://ftp.solucorp.qc.ca/pub/vserver/diffctx-2.4.11-3. This
  patch works with 2.4.12 as well. I have not released pre-compiled ker-
  nel for now.

  1. Enhancements

  1.1. chcontext and reducecap command line option

  The two utilities support the new --flag command line option. This is
  used to set some flags in the security context. For new the two flags
  are:

  + lock

     Once set, a security context is locked. It can't request another
     security context.

  + sched

     This changes the way priority is calculated for processes in a
     vserver. The priority is kind of aglomerated. A vserver running 50
     active processes will have a same impact on the server as if it was
     running a single process (roughly).

     All those flags are one-shot. You can set them, you can't unset
     them.

  1.2. vserver command: S_FLAGS support<

  The vserver command supports the new --flag command line option of the
  chcontext utility. You encode the flags (lock and sched) in the
  vserver configuration (/etc/vservers/confname.conf) like this

               S_FLAGS="lock sched"

  By default, all new vserver are created with S_FLAGS="lock".
