[Hans Zaunere]

Hello,

In regards to this thread:

http://lists.samba.org/archive/samba/2005-September/111158.html

I might be seeing a similar compatibility with this call is on Virtuozzo
based system.

> cat /etc/redhat-release
Red Hat Linux release 9 (Shrike)

> uname -a
Linux hostname 2.6.8-022stab078.9-enterprise #1 SMP Thu Jun 8 12:38:51 MSD
2006 i686 athlon i386 GNU/Linux

> mount
/dev/vzfs on / type reiserfs (rw,usrquota,grpquota)
vzfs on /tmp type vzfs (rw,noatime,nosuid,nodev,noexec)
proc on /proc type proc (rw,nodiratime)
devpts on /dev/pts type devpts (rw)


And I'm getting the following in the logs:
