Hi Guix,
“guix pack” is great for deployment of applications to servers that
don’t have Guix. For a project I have a “deploy” target in my Makefile
that essentially does this:
cat $(shell guix pack -RR -e '(load "guix.scm")' -S /bin=bin) | ssh
remote-server "tar xvzf - -C /where/i/want/it"
This is fine for small deployments, but it’s a little annoying that it
transfer *all* the files, even those that haven’t changed. So I thought
I could use rsync here, but it’s inconvenient that “guix pack” will do
what it was designed for and produce a single file bundle.
What do you think about adding an output format that is no format at all
but a file enumeration printed to stdout? That way I could use “guix
pack” to produce a list of files to transfer and use that to transfer
only the unchanged files. Alternatively, perhaps we could have a
“directory” format that merely copies (or links) the files to a new
directory root.
