Re: [Users] TinyVZ 0.7 released

TinyVZ 0.7 is a tiny little OpenVZ template for making OpenVZ containers that use the lowest amount of memory and hard disk space possible.

Re: [Users] More on making an OpenVZ template
I am using the one of debian squeeze: As a side note, one of my long-standing annoyance with Debian's software policies is that, once a given release is frozen, Debian will not update a software package unless there is a CVE-worth security bug in it. Other bugs will not get fixed. Not even if the fix is minor. They certainly will not keep current with a release in any bugfix-only branch of the software provided upstream. I can understand this software policy; open-source development is, by nature, undisciplined and a lot of developers are not very good at only fixing bugs without adding other potential bug-inducing features. Debian's policies wouldn't be a big deal, except that some Debian users have this really annoying habit of bugging upstream about a bug which has already been fixed upstream, just not applied to the appropriate Debian software repository. There is a Debian bug tracking system to file bug reports or feature requests, and Debian users are probably best using this system; if the package maintainer says it's an upstream issue, then it is time to contact upstream about the issue. - Sam ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
