Subject: [PATCH 12/19] inherit systemd environment when calling generators.
|
|
|
|
Systemd generators need access to the environment configured in
|
|
stage-2-init.sh since it schedules fsck and mkfs executions based on
|
|
being able to find an appropriate binary for the target filesystem.
|
|
|
|
With this commit I am altering the systemd behaviour since upstream
|
|
tries to gather environments with that they call
|
|
"environment-generators" and then seems to pass that on to all the other
|
|
executables that are being called from managers.
