Hi,
I don't really want to include the legacy memory stuff in my 2.6.35  
builds. To this end I've tested and uploaded the packages Ghislain  
(thanks) has sent to me with util-vserver builds for 0.30.216-pre2906.  
These completely sort out the problem, and still work with the old  
memory system.
The util-vserver-debian and util-vserver-debian-basic (this later one  
is best if migrating from Debian's own packages) packages have been  
updated in repo.psand.net. Further info on http://repo.psand.net/info/  
as usual.
Cheers,
==
