I have further improved the 'cpupower.sh' after analyzing it with shellcheck (Debian package 'shellcheck'). I am re-attaching the three files to this message, for clarity's sake. > I acknowledge that they are probably sub-optimal and could be further > generalized and/or enhanced. > But, until someone comes up with a better solution, they are better > than nothing... > The current situation is that every user has to set up ad-hoc solutions > (perhaps involving the deprecated 'rc.local' file or otherwise), unless > he/she can leverage some desktop tool... > > And, of course, any of you from the Debian Kernel Team can further > improve the files at any time. > But, please, first ship the three files in the package, without waiting > for the perfect solution. This bug report has been open since April > 2018... As Voltaire once said, the better is the enemy of the good. Please, pretty please, ship the three files with the 'linux-cpupower' package, setting the systemd service disabled by default. Let's fix this bug once and for all! N.B.: For any user who wants to manually install the three attached files *before* they are shipped by 'linux-cpupower', the commands are: # install -m 644 cpupower.default /etc/default/cpupower # install -m 755 cpupower.sh /usr/libexec/cpupower # install -m 644 cpupower.service /usr/lib/systemd/system/ # systemctl daemon-reload After this manual installation (or once the 'linux-cpupower' package ships them and installs the systemd service disabled by default), the administrator (root user) can edit /etc/default/cpupower as appropriate and then issue the command: # systemctl enable --now cpupower.service -- http://www.inventati.org/frx/ There's not a second to spare! To the laboratory! ..................................................... Francesco Poli . GnuPG key fpr == CA01 1147 9CD2 EFDF FB82 3925 3E1C 27E1 1F69 BFFE
