bug#48214: inetutils-1.9.4 build fails

[Ludovic Courtès]

Hi,

Bone Baboon via Bug reports for GNU Guix <bug-guix@gnu.org> skribis:

The ‘core-updates’ branch contains updates to core packages and core
Guix functionality that entails a rebuild of all the packages.  In that
branch we put package upgrades that would otherwise lead to too many
rebuilds (info "(guix) Submitting Patches").

No: ‘guix refresh -l inetutils’ shows that almost 2,000 packages depend
on inetutils.

That said, if needed, ‘master’ could provide 2.0 in addition to 1.9, as
is done for GDB for instance.

You can do better :-), you can install 2.0 from master like so:

  guix install inetutils --with-latest=inetutils

‘core-updates’ is where we put core changes as I wrote, including
experimental changes.  That branch also does not receive security
updates in a timely fashion.  So it’s really a branch for developers
working on core improvements.

HTH!
