Re: Despite the documentation, "etcupdate extract" handles -D destdir (and its contribution to the default workdir)

The "etcupdate extract" material does not show -D destdir as valid.


Thanks, it was a documentation oversight I've just fixed.  It is definitely
supposed to work and is quite useful for cross-builds (e.g. I use it frequently
to update rootfs images I use with qemu for RISC-V or MIPS that I run under
qemu, or when updating the SD-card for my RPI that I cross-build on an x86
host).

Re: etcupdate -p: No previous tree to compare against, a sane comparison is not possible. (was: Review D28062 …)

Hmm, how did you initially install this machine?  Release images should
generally include a pre-populated /var/db/etcupdate so that etcupdate
works.  If you don't have one of those, you will have to perform an
initial bootstrap of etcupdate (only once) by running 'etcupdate
extract'.
If you do this before you update /usr/src then 'etcupdate' will later
work fine.  If you are doing this after you have already updated
/usr/src, you will need to run 'etcupdate diff' after 'etcupdate extract'
and fix any unexpected local differences in the generated patch, e.g.
by copying files from /var/db/etcupdate/current/etc to /etc.  Once
you have done this, 'etcupdate' will work fine on the next upgrade.

However, I'm curious how you didn't get the etcupdate bootstrap when
you initially installed.



Sorry for not replying sooner.

It's not an answer to your question, but might the thread at

be relevant?


Yes, you might indeed have hit this bug (which has since been fixed).
You might have to 'etcupdate extract' and then manually review
'etcupdate diff' to see if you have any unexpected diffs to recover.
Sorry. :-/

Wow.. Best update I have done in years. At least for me 12.2 > 13.0 was 
great.  Great job !
