Bug Description

In /etc/cron.daily/find is ionice used when starting updatedb. The is
... ionice -c ${IONICE_CLASS:-2} -p ${IONICE_PRIORITY:-7} updatedb ...
So the option -p is used to set the priority. But ionice uses -p to set a specific process ID and to
set the priority the -n parameter must be used.
On some installation (I cannot tell what the difference is), this produces an error. On others the -p
seems to be ignored.
This seems to be introduced by Bug #134692.

The reason why sometimes (on some installations) no error is reported, is of course if the 'priority' given with -p is a current valid process ID. Which means that this process is changed by ionice instead of calling updatedb.
