Re: [vserver] Concurrency issue in /proc?

Hi,

I tried with util-vserver and I can't reproduce the problem either on
an 8 core server.

However I noticed that Jacque's tools mount /proc once for each vserver:

none on /vservers/v1/proc type proc (rw)
none on /vservers/v2/proc type proc (rw)
none on /vservers/v3/proc type proc (rw)

However with util-vserver from the root server I don't see extra
mounts for /proc.

How is /proc made visible inside the guest?
