rebase by setup

rebase by setup

[Buchbinder, Barry (NIH/NIAID) [E]]

Running setup in unattended mode runs rebase even if nothing is
installed.  Is this intended/necessary?

I run setup every day when I boot and rebasing is time consuming.
Not really a problem but it is annoying.

Thanks,

I would expect it to re-run *everything* not marked .done in /etc/postinstall, and the autorebase script is never so marked.

The autorebase mechanism has a “fast” mode, which should be running, as opposed to the “full” mode, which is slower.  Verify that by the existence of /var/cache/rebase/fullrebase.done.

(Yeah, that’s right, watch me flex my new autorebase muscles.  Beware the Dunning-Kruger effect!)

If nothing has changed, then besides the check if there is something new to
rebase nothing is actually done by autorebase.  That check looks up the
timestamps of the files in /etc/setup, so unless you have some truly awful
disk performance or something is mucking with the timestamps this shouldn't
take long.
