Bug#875303: Troublesome systemd-networkd-wait-online.service

Package: systemd
Version: 234-3
Severity: normal

The systemd-networkd-wait-online.service is causing tlp.service (among
others) to break in my setup.

The issue is caused by the rule


present in systemd-network.service. Several services include include an
explicit dependency on network-online.target which then drag in
systemd-networkd-wait-online.service. One is apt-daily.service, but
exim4 (via LFS) is another.

The net result is that multi-user.target now depends on
systemd-networkd-wait-online.service. However, on a laptop, this is
broken. multi-user.target shouldn't directly depend on a working

In case of tlp.service, which has After=multi-user.target, will execute
the startup rules *after* wait-online timeouts, which is some minutes
after I could login.

Incidentally, exim4 also isn't started until timeout occurs, which makes
local mail delivery broken until then.

This is more subtle. The init script in this case depends on $network.
systemd shouldn't automatically translate this to include
network-online.target, but only network.target.

I currently masked network-online.service to resolve this issue, but
this shouldn't be. Services should be able to depend on network-online
without affecting system startup.
