[Message part 3 (text/plain, inline)]

I've seen this when updating systems, but it seems like something is
wrong with the handling of nss-certs.

I'm on a guix revision with nss-certs by default, and when I add
nss-certs to my system packages (to simulate not removing it when
upgrading), it breaks certificates (e.g. wget https://guix.gnu.org/
doesn't work).

My reading of the operating-system-packages code suggests that adding
nss-certs shouldn't have any effect, but this doesn't seem to be
working.

Apparently having multiple nss-certs of the same version is no problem
(they get deduped later).  The original problem would thus only exist
when there are multiple versions of nss-certs listed in packages, as
could happen for installer-generated configs that use
'(specification->package "nss-certs"), which would pick the latest
version and clash with the one in %base-packages.

My code could call delete even in the first case, which would clear
*all* nss-certs because they were the same object.  That's now guarded
against in 35ae95061e1b843e1df069693177519f22f9a16d ("system: Do not
delete all nss-certs packages when they are the same object."), which
I've just pushed.

Closing.
