Already done that a month or so ago, to satisfy my own curiosity, the answer
is yes host lookups did fail again without it.
And just to make sure, I just went to it, removed the lsattr i, from
resolv.conf, commented that line and rebooted.
Why on earth did you reboot? Just edit the file, ping something, see
whether it works, and if it doesn't work, SHOW US THE DETAILS!
Just to make sure there wasn't any leftovers.
I can ping yahoo.com just
fine, but this machine, 20 feet of cat5 away, is Name or service not found,
no local network IOW.
Please show us at least the following:
An sh -Y into bpi54 still works. So: copy/paste both directions.
cat /etc/debian_version

Also, anything else that you can think of that I might have forgotten.
We *really* need to know how to reproduce this.
I note my #comment has been removed from resolv.conf, so network mangler
has been there and rewritten it. That is the reason I normally do a
sudo chattr +i /etc/resolv.conf
as soon as I save after adding my "search hosts, nameserver" line to it,
otherwise Network Mangler will destroy it as it is right now.
Your turn, I'm going back to bed.
