guix installation age warning sometimes wrong

guix installation age warning sometimes wrong

About 125 days ago, I updated my root profile's ".config/guix/latest"
symlink to point to my primary user's guix package definitions:

  # ls -l /root/.config/guix/latest
  lrwxrwxrwx 1 root root 32 Mar 21 15:00 /root/.config/guix/latest -> /home/sankey/.config/guix/latest

I did this because I didn't want to run `guix pull` twice every time,
once as root and once as my normal user.  Since then I've been keeping
up to date, running `guix pull` frequently as my normal user.

But now when I invoke guix as root, it constantly tells me:

  guix package: warning: Your Guix installation is 125 days old.
  guix package: warning: Consider running 'guix pull' followed by
  'guix package -u' to get up-to-date packages and security updates.

...presumably because it's reading the mtime/ctime on the symlink.  Is
there a more precise way to asses the age of the guix installation
symlink?

Troy

This has been discussed previously, for example in this thread:

Yeah currently this is based on the mtime.

Eventually I think we’ll rather check the Git commit that this
corresponds to, compared to the latest one available (though that’s
tricky since it involves making a network connection.)

So that’s what we have for now.  As long as you don’t fiddle manually
with the ‘latest’ symlink, everything should be fine; otherwise be
prepared for things like this.
