So I have an environmentfile containing two variable definitions:
RUNASUSER=nobody
MEM=4294967296
And my service section reads:
[Service]
EnvironmentFile=/path/myfile
User=$RUNASUSER
LimitMEMLOCK=$MEM
This service failes to startup, as I cannot seem to being able to use a
variable for the User attribute, but I may very well for LimitMEMLOCK.
Error:
Failed to determine user credentials: No such process
And if specifying instead:
[Service]
EnvironmentFile=/path/myfile
User=nobody
LimitMEMLOCK=$MEM
Everything does work. And I am wondering, why? And moreover, is there
any source of documentation, that lists or even explains, what
attributes may have a variable as an argument and what do not?
As for instances/template units it would be really helpful to being able
to set the running user in the configuration/environment file. Or at
least have a knowledge of those settings, that do not allow this, for
what reason ever. Especially when talking about directory settings.
