Package: man-db
Version: 2.5.6-2
Severity: normal
G'day. I don't know if this is correctly a man-db bug, or a dpkg bug:
Since man-db has started using start-stop-daemon in the daily and weekly
cron.d scripts it has been failing to run inside the OpenVZ containers I use
to provide "virtual" machines for a bunch of services.
Specifically, this failure:
/etc/cron.daily/man-db:
start-stop-daemon: Unable to alter IO priority to mask 24583 (Operation not
permitted)
run-parts: /etc/cron.daily/man-db exited with return code 2
The second line is no great surprise: within the virtual environment (VE)
access to various kernel level features, including setting your own I/O
priority, is deliberately restricted.
Having the man-db nightly processes run with a lower I/O priority is nice, but
at this point it doesn't run them at all inside the VE because of this
invocation.
It would be good to consider that a non-fatal error. I notice, in fact, that
man-db already tries to work around the free 'vserver' environment.
If you want to continue to do that I suggest either using the 'virt-what'
tool, which makes it a problem for someone /else/ to identify every new VM
type out there, or to make the failure to set an I/O scheduler non-fatal.
However, to detect running inside an OpenVZ VE you can check for
/proc/user_beancounters (deprecated, but present), or /proc/vz/{veinfo,vestat}
existing.
Determining the different between the "hardware" node, which can set I/O
priority, and the VE, which can't, is best done by checking for the absence of
/proc/vz/version, I think.
Regards,
Daniel
