So when / how often does readahead-collector run now?

Thanks,

Every month.

/etc/cron.monthly/readahead-monthly.cron

It'd be interesting to do a daily yum update / reboot and see how the
boot times look, graphed for a couple months.

Will things degrade until the next collection run?  I wonder if some
inotify magic might be interesting; if more than X% of the
previously-collected files have changed, then kick the collector on again?

hehe, yes, but how would you implement that? :) I don't think this is doable :)

A yum-readahead plugin could look at the readahead list after an upgrade and calculate if refreshing is needed.
