Crochet has some experimental hooks to install packages onto the system being
built, but this seems to be hitting problems due to limitations in 'pkg -c'.
In particular, it seems that pkg performs the chroot before it does any network
lookups. This is a problem if the chroot is not a complete system environment
(which it cannot be when you're building an image for another system).
There's some further discussion on github:
I'll reply directly to github thanks for pointing me to the ticket
As people might only follow this thread and not the ticket here is what I

the problem with pkg -c is that it calls chroot very early. To avoid that
problem we have added pkg -r which does not perform any chroot at all therefore
having not network issue, but the ports tree are is not yet entirely aware of it
and some scripts (preinstall/postinstall) might cause some issues.
at least creating users from the script is safe in that regard. for most simple
case that should work.
As Bapt knows (I've been harassing him) pkg needs an "install all this
over there" mode.
The answer is "-r" but it does suffer from the fact that it requires
postinstall scripts to cooperate

I've used three different methods to get around this..
1/ use -c and prepopulate it with a copy of /rescue, and copying all
the pkg files I need in first into /pkg, which I delete afterwards.
I'd like clarification in the Man page about setting a good $PATH in
the chrooted part of pkg currently I just copy /rescue into /bin but
pkg seems to sometimes use full paths for things so that meant also
/usr/bin and usr/sbin. (or maybe that was an install script.).
(in my application I could just link all 4 locations to be the same
2/ use PKG_DBDIR=$(TARGET_DIR)/var/db/pkg pkg add --relocate
Almost the same as -r from my perspective.
3/ because I need to work as non-root, and pkg doesn't have a -u and
-g option like chroot does, there are times when I need to do:
sudo chroot -u $ME -g $MYGROUP sh -c "INSTALL_AS_USER pkg add -f -M
instead of using pkg -c.
I worked up a patch for -u and -g but lost it.. it was only about 20
lines including the usage() change. I'm sure bapt could redo it much
using -u automatically enabled install_as_user.
I was thinking that in order to do this properly the chrooted child
should do all it's fetch requests etc via the non-chrooted parent, but
that would have probably been a bit too complicated. (including add
