Title:
systemd resolv should separate the output of stdout and stderr
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Eoan:

Status in systemd source package in Focal:

Bug description:
[impact]
dhclient fails to notify resolved about DNS servers due to bash-
specific redirect inside 'resolved' hook script
[test case]
see original description below
[regression potential]
any regression would likely cause resolved not to be aware of
dhclient-provided dns servers
[other info]
This is needed only in Eoan and later; X/B/D do not have the bash-
specific redirect '&>' in their hook file.
The change that originally added the &> to eoan is also being applied
to b/d in bug 1805183, but with this fix added also.
original description:
---
The file /etc/dhcp/dhclient-enter-hooks.d/resolved
provided by systemd (242-7ubuntu3) causes the dhclient failing to get DNS due
to systemd-resolved is not run.
This issue can be reproduced on Ubuntu Eoan:

Attached please find the patch for this. The output for md5sum in the
hook file resolv should separate the stdout and stderr so it won't
compare the wrong data.
