Thank you, that’s what I wanted to use, but I am not really sure how
to do it with systemd units?
I failed by adapting the systemd-logind Exec line, as the permissions
for the perf counters(?) are not there.
Then I tried to add a perf service unit doing
/usr/sbin/perf_4.17 record -o /dev/shm/perf.data sleep 10
and order it before sysinit.target but that did not contain anything
useful.
Kind regads,
Paul
