for debian stable ("lenny"/5.0) util-vserver 0.30.216~r2772-6 worked for my
particular use-case until i enabled cgroup cpu scheduling, and then the
only thing that broke was executing a command in a guest by way of
util-vserver (instead of using a service started directly/indirectly by
"vserver ${GUEST} start") didn't add the new process to the guest's group.
the attached patch fixes that problem and is a smaller change than
upgrading util-vserver. this mirrors debian's policy of only applying
minimal patches to fix packages in a stable release instead of introducing
a whole new version (and potentially more/different bugs).
the patch is really only one line, but i'm a dot-the-i-and-cross-the-t kind
of guy, so i had to make the surrounding indentation uniform.
my use-case is:
* 2.6.27.y kernel
* vs2.3.0.36.6 patch
* debian lenny host
* debian lenny & etch guests
* vhashify
* cgroup cpu scheduling
* no disk quotas (yet)
while investigating a failure testfs.sh was reporting, i did build a recent
version of util-vserver and it appeared to work fine in my testing of
testfs.sh (however limited), but i didn't use it beyond that because the
version of util-vserver in stable works for me (and has for the last 6
months with the exception of my one-line patch).
