Well, I am not sure if it fits your use case but I am still annoyed to
find the “profile/manifest“ path when I use:
guix pack -f docker --save-provenance -m manifest.scm
then extracts this “profile/manifest” needs:
--8<---------------cut here---------------start------------->8---
docker export -o foo.tar <ID>
tar -xf foo.tar $(tar -tf foo.tar | grep ’profile/manifest’)
--8<---------------cut here---------------end--------------->8---
in order to rebuild an approximation of ’manifest.scm+channels.scm’ if it
has been lost, for example to be able to re-run at anytime:
--8<---------------cut here---------------start------------->8---
docker load < $(guix time-machine -C channels.scm \
-- pack -f docker \
-m manifest.scm)
docker run -ti <TAG>
--8<---------------cut here---------------end--------------->8---
For reference, see <https://yhetil.org/guix/86sgb9nt4k....@gmail.com>.
Therefore, I do not know if this output format is helping for this.
Thanks,
simon
