Subject: tests: allow running all the services with SYSTEMD_LOG_LEVEL
X-Git-Tag: v251-rc1~286
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bf6ef6b6a9156e5f52ee69ce0c529a246f103e54;p=thirdparty%2Fsystemd.git

tests: allow running all the services with SYSTEMD_LOG_LEVEL

It should make it easier to figure out what exactly services do there.
For example, with SYSTEMD_LOG_LEVEL=debug userdbd (v249) prints
```
varlink-5: New incoming message: {"method":"io.systemd.UserDatabase.GetUserRecord","parameters":{}}
```
before it crashes and systemd-resolved prints
```
varlink-21: New incoming message: {"method":"io.systemd.Resolve.ResolveAddress","parameters":{"address":[127,0,0,1],"flags":0,"ifindex":1000000,"family":0}}
```
and those messages are helpful (especially when scripts causing them
aren't clever enough to keep track of random stuff they send to systemd
:-))
