Package: pm-utils
Version: 1.4.1-15
Severity: important
Approximately every second the pm-utils scripts write this junk to my
/var/log/pm-powersave.log file:

-------------------------->8=======================
This creates log files that quickly grow to many gigabytes. Last I
checked, the log file was at 23GB on a 37GB root partition. Since
logrotate is used to rotate these logs (and logrotate is a amateur-ish
hack that doesn't rotate logs in real-time like daemontools or runit),
the files can easily grow too large for the partition with no
monitoring.
So there are multiple problmes here in design and implementation:
A. Something is causing events to be generated every second. I don't
know what that is. Is this normal?
B. The logs are too verbose by default, but don't really help a normal
person understand what is going on.
C. The logs don't have any timestamps associated with them.
Distinctly unhelpful.
D. The logs don't rotate off in a sane way, based on a fixed size or
other metric that prevents pm-utils from DoSing the system. Try
runit's svlogd.
All of this churning every second not only wastes my disk space, but
it also burns precious battery life and degrades the life of my SSD.
Isn't the point of something like pm-utils and "powersave" mode
supposed to work in the opposite direction? Hence the "important"
rating for a package of this kind.
Thanks,
tim
