Re: Identical files across subsequent package revisions

Hi again,

Sorry, I have not finished my previous email.  Wrong keystroke in the
wrong buffer because misuse of the Ludo’s code. :-)

What I wanted to illustrate is “revision” does not mean “new version“
and I do not know what is the typical usage by people; aside Guix
dev. :-)

How many times per week or month people are doing “guix pull && guix
upgrade” almost blindly without reviewing what is new?


Last, I was trying to understand what is the “revision” number
corresponding to which outputs.  For example r-minimal:

<https://data.guix.gnu.org/repository/1/branch/master/package/r-minimal/output-history>

There are 3 outputs with 4.0.3, so I am expecting 3 similar revisions in
the chart.  Then 3 others with 4.0.2, then 2 others with 4.0.1.

In the 6 revisions in the chart, I was trying to figure out what does
mean the ’0’: r-minimal against which other one, i.e., which Guix commit
against which other one.  Idem for 1,2,3,4,5. :-)


BTW, really interesting topic!  Thanks Ludo. :-)

Cheers,
simon
