A set of environment variables used in the user environment.
|
||
|
|
These variables will be set as systemd environment
|
||
|
|
variables, using `environment.d`. The value of each
|
||
|
|
variable can be either a string or a list of strings. The
|
||
|
|
latter is concatenated, interspersed with colon
|
||
|
|
characters.

`hjem.users.<name>.environment.variables` and

`config.environment.variables`. This may lead to conflicts.

unset it manually in `environment.extraInit` (`unset ${name}`).
