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

1 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) :
3 * Starting haveged ... [ ok ]
4 /lib/rc/sh/ line 87: /sys/fs/cgroup/openrc/rngd/tasks: No such file or directory
5 * Starting rngd ... [ ok ]
7 And indeed, that directory is missing. A restart of the appropriate service however creates those entries. The Gentoo bug entry tells me :
9 "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."
11 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 ?
