make.conf contains
WRKDIRPREFIX= /usr/obj
which builds ports in /usr/obj/usr/ports/folder/port/work
The comment says "move work area out of unionfs".
What does it mean?
This is a true story... /usr/ports is mounted into the chroot via unionfs. Building packages on top of a unionfs corrupts the package so that package installation on ZFS partitions fails. We don't know the details or have the time to inspect this further, so we have this workaround.
I'm confused... I didn't mount /usr/ports, I cloned it from the opnsense ports repo.
and I don't see any unionfs partitions
# mount
/dev/ada0s1a on / (ufs, local, soft-updates)
devfs on /dev (devfs, local, multilabel)
devfs on /var/dhcpd/dev (devfs, local, multilabel)
Maybe we're talking about 2 different things. I'm not trying to build an image. I just want to use ports to add or recompile some packages.
You can zap WRKDIRPREFIX for local builds. It is only used for tools.git "make ports", which runs in a chroot with the unionfs trick
Got it, thanks!
