[Bug 1579580] Re: ureadahead reports relative path errors in journalctl output

[WinEunuchs2Unix]

I was checking for my own log messages I was writing and found this:

$ journalctl -b | grep eyesome | grep ureadahead
Oct 07 11:15:25 alien ureadahead[289]: ureadahead:acpi-lid-event-eyesome: Ignored relative path

I found this bug report and ran the recommended check:

$ journalctl -b | grep ureadahead | grep relative | wc -l
6474

As I have multi-boot logging enabled I did some percentage tests:

$ time journalctl | grep ureadahead | grep relative | wc -l
14875

real	0m8.072s
user	0m7.991s
sys	0m3.153s

$ journalctl | wc -l
907683
$ journalctl -b | wc -l
10504

For all boots ureadahead spam is 14875/907683=1.63% of all lines
For current boot ureadahead spam is 6674/10504=63.53% of all lines

I went back through all boot logs:

$ for i in $(seq 1 145); do journalctl -b-$i | grep ureadahead | grep
relative | wc -l ; done

Booting 135 times ago also had ureadahead spam:

$ journalctl -b-135 | grep ureadahead | grep relative | wc -l
3751
$ journalctl -b-135 | head

If someone wants more journalctl details I'd be happy to provide.
