[gentoo-dev] /sys/fs/cgroup/openrc/???/tasks sometimes missing

2014-06-03 Thread Toralf Förster
If I boot a 32 bit stable Gentoo Linux as a user mode linux guest with current 
kernels (host is a 32 bit stable Gentoo too), then I do observe sometimes 
during the boot process error messages from the init system of Gentoo (OpenRC) 
like the following (for subsystem rngd in this example) :

 * Starting haveged ... 
  [ ok ]
/lib/rc/sh/rc-cgroup.sh: line 87: /sys/fs/cgroup/openrc/rngd/tasks: No such 
file or directory
 * Starting rngd ...
  [ ok ]

And indeed, that directory is missing. A restart of the appropriate service 
however creates those entries. The Gentoo bug entry 
https://bugs.gentoo.org/show_bug.cgi?id=489386 tells me :

It's known race in cgroups, I'm going to address this issue on one of the 
following weekends. The problem is that issue is not reproducible on my 
systems.

but  that's all since 5 months. Now I'm wondering if this just happens for an 
UML guest and who knows how to fix it ?
