[PATCH 0/5] Add support for the RPM format to "guix pack" |
|
Date: |
Fri, 3 Feb 2023 11:19:26 -0500 |
Hello Guix!
This series adds support for the RPM format to "guix pack", so that one can
generate an RPM archive via e.g. "guix pack -f rpm hello", and install it on
their favorite RPM-based GNU/Linux distribution. With the exception of the
payload compression, the generation of the archive is fully handled in Scheme,
which ended up being tricky, with the documentation about the RPM binary
format being scarce. Most of the problems encountered were figured out
stepping an 'rpm' command invocation in GDB, which felt a bit like reverse
engineering!
Anyway, the end result appears to work well and has few dependencies (compared
to using 'rpmbuild', as most other projects do), so I think it was worth the
effort.
Thanks!

Done, thank you!

Thanks for sharing your feedback! I could reproduce the experiment in
an old RHEL VM, and indeed, identical files do not seem to cause
conflicts, which is awesome for our use case! I've modified the doc as
follow:

With this, I've now pushed the series to master, after running 'make
check TESTS="tests/rpm.scm tests/pack.scm"' one last time.
Enjoy!
Closing.
