Dear guix,

When I boot my system on core-updates-frozen, I get an error message:

/gnu/store/xxx-openresolv-3.12.0/sbin/resolvconf: line 824: mkdir: command not found
Failed to create needed directory /var/run/resolvconf

I didn’t experience any DNS issue, but my network is simple on that
machine. In any case, I think it would do no harm to wrap resolvconf to
set its path to the coreutils so that it can find mkdir and rm. I didn’t
find resolvconf to invoke any other program.

What do you think?

Best regards,

Vivien
