Bug#1111073: power-profiles-daemon: systemd service does not start after update to trixie

[Matteo Settenvini]

Package: power-profiles-daemon
Version: 0.30-1.1
Severity: grave
Justification: renders package unusable

Dear maintainer,

the service does not start anymore with the provided systemd unit file.
Just attempting:

  systemctl start power-profiles-daemon.service

hangs. This is after an update to trixie, but I don't have any service file
overrides (it is the stock version from the package).

Trying to start the program manually as root works:

  /usr/libexec/power-profiles-daemon &
  powerprofilectl list

shows all the profiles. There must be a too-restrictive setting in the unit
file which prevents running. Nothing is shown in the logs, though.

The interesting part is that invoking `systemctl start power-profiles-daemon`
does not show any forked process for `power-profiles-daemon` by doing `ps ax`.

I wonder if this is something wrong in systemd / a feature missing.

Cheers,
Matteo Settenvini
