I plan to work on fixing the "resource-hungry cron jobs run when
laptop is on battery" problem. My current plan is to do two things:
- First, separate the system cron jobs to "should run on schedule"
(e. g. logwatch) and "can be delayed" (e.g. prelink), probably by
This is policy, independent of the cron mechansim; replace cron
by something newer and greater for all I care.
Then glue this into the current cron/anacron combination so that
the cron.delayed jobs are not run on battery, and scheduled to run
when the laptop is plugged in.
- Second, replace slocate by something smarter.
E.g. it should be possible to just record (ctime, mtime) of all scanned
directories and use the preexisting database to avoid reading
unchanged directories each time: on my system this would reduce
the amount of data updatedb has to read from the filesystem from 70 MB
to 3.6 MB.
Bill Nottingham has proposed a daemon using the audit subystem
to watch for filesystem chages.
