Description Scott Bertilson 2015-09-22 20:01:53 UTC

At the least, could the dmesg logging rename the previous so that it is at least possible to compare a previous bootup with the current one?

Ideally, it would be great if there could be a specifiable number of previous instances saved.

Reproducible: Always

I just modified bootmisc to optionally save the previous dmesg log to
/var/log/dmesg.old. That gives you the ability to compare the  previous
log to the current one. This change is in commit ee94455.

I will consider making it save more logs, but this gets you started.

Thanks for the report.
