[gentoo-user] [OT] What's happened to BOINC recently?

[Peter Humphrey]

Hi list,

Recently I've been finding that BOINC has just stopped. It doesn't show up in
ps -ax and I can't see anything helpful in its logs. Every time I query its
status I get this, which is new:

$ /etc/init.d/boinc status

mkdir: cannot create directory ‘/sys/fs/cgroup/openrc/boinc’: Permission denied
 * status: started

I installed BOINC from the ebuild, not by getting it from berkeley.edu. The
only changes I've made are to install its data directory under my home
directory (/home/prh/boinc), added myself to the boinc group and chown'd
everything to prh:prh.

I had tried keeping the default user, group and directory but I found it
easier to do it this way.

Can anyone shed any light on this?

FYI I got these errors simply when I queried the status of a service
as a normal user, rather than root, but the final status line was
still correct IIRC (on systemd now though, can't verify).  Was on
hardened at the time, if that matters.

Ah, so that's what's changed - thanks.

I wonder why querying the status of a service requires the creation of 
directories under /sys/fs/cgroup. Also whether I can configure cgroups in the 
kernel somehow to allow an ordinary user to query a status, as used to be 
possible without throwing errors. This is indeed an openrc system, as you 
imply, there being nothing to push me towards systemd since I don't run gnome.

That just leaves the mysterious stopping of BOINC to watch out for.
