[Bug 2046688] [NEW] powertop generates incorrect file in /var/cache/powertop

[Ryan Harper]

Public bug reported:

1.

# lsb_release -rd
Description:	Ubuntu 22.04.3 LTS
Release:	22.04

2.

# apt-cache policy powertop
powertop:
  Installed: 2.14-1build1
  Candidate: 2.14-1build1
  Version table:
 *** 2.14-1build1 500
        500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
        100 /var/lib/dpkg/status

3.

powertop.service runs correctly, and powertop --auto-tune works

4.

powertop.service status shows inactive/dead, powertop --auto-tune says
it will start once it's run for th e mine time.

The issue is that powertop generates this file:

root at thiolized:/var/cache/powertop# ls -al 
total 4
drw-------  2 root root   36 Dec 17 20:58 .
drwxr-xr-x 17 root root 4096 Dec 17 20:58 ..
-rw-r--r--  1 root root    0 Dec 17 20:58 saved_results.powertop


but, the systemctl service and powertop tool is looking for

/var/cache/powertop/saved_parameters.powertop


Please patch the powertop program to either generate saved_results.powertop, or change it look for saved_results.powertop.

Note, a simple symlink is sufficient to fix the service.

ln -s saved_results.powertop saved_parameters.powertop

# ls -al
total 4
drw-------  2 root root   69 Dec 17 21:07 .
drwxr-xr-x 17 root root 4096 Dec 17 20:58 ..
lrwxrwxrwx  1 root root   22 Dec 17 21:07 saved_parameters.powertop -> saved_results.powertop
-rw-r--r--  1 root root    0 Dec 17 21:09 saved_results.powertop
