instead of bash code.

Make cgclear quiert when there is nothing to clear.

2009-12-22T08:24:04+00:00

Cgclear clears and unmounts all controllers. Therefore I think it's not an
error when there is nothing to clear and unmount.

Use cgclear on shutdown

2009-12-22T08:23:53+00:00

Use cgclear on service cgconfig stop, it's much faster than manual group
removal.

Don't create sysdefault group whent it's not needed

2009-12-22T08:23:42+00:00

IMHO most of users don't need sysdefault group being created during boot -
it's quite slow and at least in Fedora there is no application using it.

So, let users to configure it and allow them to turn the sysdefault off.

Whether the option should be enabled/disabled is distro-specific, we as
libcgroup turn it on.

Changelog:
 - create the sysdefault group by default

Fix reading of empty parameter values

2009-12-22T08:16:48+00:00

When a group parameter has empty value (like uninitialized cpuset.cpus),
libcgroup does not return this parameter value - it returns
ECGROUPVALUENOTEXIST instead.

I think reading whole parameter file instead of just '%s' is the right thing
to do - it helps also with multiline values, like cpuacct.stat.

Fix error text on failed reading of parameter.

2009-12-22T08:16:45+00:00

ECGROUPVALUENOTEXIST is translated by cgroup_strerr to "Cgroup trying to set
value for control that does not exist". This is wrong, because the error
code is being returned also when *reading* non-existing value,

I propose "Cgroup, requested group parameter does not exist".
