Subject: [PATCH] test-execute: also mount tmpfs on /dev/shm
|
||
|
|
|
||
|
|
Otherwise, if /dev/shm has a directory that cannot be accessible by
|
||
|
|
unprivileged user, then we cannot pick a dynamic user, and test service
|
||
|
|
may fail with unexpected error code:

Failed to enter shared memory directory /dev/shm/systemd-watch-bind-BqAGlN: Permission denied
