Re: Summary/Minutes from today's FESCo Meeting (2020-05-11)
Once upon a time, Igor Raits <ignatenkobrain(a)fedoraproject.org> said:
* #2381 F33 System-Wide Change: systemd-resolved (ignatenkobrain,
15:10:20)
* AGREED: APPROVED (+4, ±5, -0) (ignatenkobrain, 15:18:40)
* AGREED: APPROVED (+5, ±4, -0) (ignatenkobrain, 15:20:51)
* AGREED: APPROVED (+6, ±3, -0) (ignatenkobrain, 15:21:23)
So, this is kind of annoying. Last week's meeting had this as "Post
feedback on the devel list and restart discussion"... but that never
happened.
This change means applications will no longer be able to find the
working DNS servers for any kind of lookups not handled by systemd
(systemd-resolved is intentionally not a true DNS server). The only
interface for that has been /etc/resolv.conf, but as I understand it,
that will go away (replaced with a stub that refers to 127.0.0.53).
If actual DNS servers are not going to be listed in /etc/resolv.conf,
then there needs to be a well-defined way for applications to discover
the current DNS servers. resolv.conf has been the way to find DNS
servers for decades; dropping it (and with no clear replacement) is a
bad idea.
