[Bug 1731130] [NEW] /run/resolvconf/resolv.conf contains invalid 'search' entries

[Paul Natsuo Kishimoto]

Public bug reported:

STEPS TO REPRODUCE:

I connect to certain MIT networks via both wired and wireless
connections.

Afterwards, I connect to a home network.

EXPECTED:

Domains like http://web.mit.edu resolve.

OBSERVED:

They don't.

The file /run/resolvconf/resolv.conf contains only these lines:

nameserver 127.0.0.53
search mit.edu hsd1.ma.comcast.net

It would seem hsd1.ma.comcast.net is correct, since that describes my
ISP. But the mit.edu is erroneous and prevents applications from
correctly resolving mit.edu domains.

If I manually edit this file and remove "mit.edu" from the search line,
the domains then resolve correctly. Shouldn't this be removed
automatically?
