freebsd stable - May 2008 - Jail resource limits

http://wiki.freebsd.org/JailResourceLimits

Is this anthing people are working on? Is it on its way to RELENG_7?
Is there a 7-version of the patch or anything? This would be a _VERY_
useful feature.

Hi,
AFAIK nobody is working on it. A year ago there was newer release of the 
patch against CURRENT at that time (FreeBSD 7) [1] 
http://www.ualberta.ca/~cdjones/jail-cpumem-current.tgz
I never test this patch on current, only version for 6.x and if patch 
for current were made without improvements, it contains same bugs as 
patch for 6.x (eg.: not showing memory usage).

There are some other guys trying to do the same, but I never saw patches 
published.
Andrew Snow - Jails as a VPS [2]
Alex Lyashkov - Jail2 aka FreeVPS [3a][3b]

Or fixes for C.D. Jones work:
Chris Thunes - jtune not showing resource usage - fixed [4] (note - 
attached patch is reversed) [5]

So as you can see, there were some talks about Jail improvements for one 
year existence of this mailinglist (freebsd-jail@freebsd.org), also it 
is two years from SoC [6] and we still don't have anything commited to 
7.x or to CURRENT. It is sad. There is little attention to jails, only 
few people are able to do some coding work etc.

If the are somebody with skills and time to resurrect some mentioned 
projects, I am willing to help with testing.

Also it will be good to have some up-to-date wiki page with "all the 
patches" (resource limits, SysV IPC, multiple IPs...) and status of this 
work, so people can easily find and try it.

Are you willing to update the existing wiki page? If yes register to  
the wiki (default style would be MiroslavLachman as the username) and  
I give you write access to the page.

Bye,
Alexander.

I will also be happy to help in whatever way I can. I have no coding- 
experience to talk about. But testing in various env
and so on. (and help with docs/wiki)

Maybe it will be a good idea to create a new page that puts all jail- 
stuff in one place. I mean, there is more to this then just resource  
limits.
