Hi Austin,

And thanks for your detailed report.

netcfg is the component responsible for forwarding network settings from
the installer's context to the installed system. A few bugs were fixed
that led to having no /e/n/i configuration for wireless interfaces in
the non-NetworkManager case, and I cannot exclude the possibility I
might have introduced a regression for the NetworkManager case.

It feels a little strange that such a big issue wouldn't have been
spotted via the many tests that are run for the release, but maybe we
aren't actively checking that particular point (yet)…

Could you please share /var/log/installer/syslog (compressed) via
