files/legacy.conf change request
This was changed intentionally by systemd upstream. Notably, they never used the "uucp" group, and instead used a dedicated "lock" group. https://github.com/systemd/systemd/commit/e1ab991283ca1072d29e21d8af76e992b663ad9b However, that too has since been removed. https://github.com/systemd/systemd/commit/61f32bff6130a44d077886d38cff89ad161bf177 If you really want the old behavior, you can create your own "legacy.conf" file in /etc/tmpfiles.d. > Expected Results:
> java apps should be able to use serial ports
What java apps are you referring to? The modern way to reserve a serial port is using flock(), so maybe your apps just need an update.

If /run/lock already exists, its permissions will not be altered.

With the version you pushed, I could overwrite /run/lock with my "non-standard" config based on /etc/tmpfiles.d Thank you very much! |
before sys-apps/systemd-utils-252.4:, /run/lock was drwxrwxr-x 2 root uucp 80 since thenm it is drwxr-xr-x 2 root root 80 This lock folder is used by serial ports users (java), which are in uucp group. With this new right, they cannot use a serial port anymore. These rights are pushed by files/legacy.conf installed in /usr/lib/tmpfiles.d Could it possible to change files/legacy.conf so that it was before? Reproducible: Always Actual Results: java apps cannot use serial port anymore Expected Results: java apps should be able to use serial ports
