I have a GNU Guile package, which I created using guile-hall.

I know the 2 commands, but maybe there are others?

I don't know which one of the 2 results (they differ) from the 2 commands one
should write in ones package definition to add to guix/gnu/packages/guile.scm. I
can paste any hash there, but which one will be the correct one? Both commands
seem appropriate to me. The tarball is after all built from the sources in the
directory and I could calculate the hash of the directory, or the one of the
tarball. That is what confuses me.

Basically I am asking for a general guideline. How is it usually done? How is it
done for packages created using guile-hall?

I don't want to send in a patch with a wrong hash in the package definition,
which only costs time for anyone, who reviews.
