changing permissions of /sbin
On my single user system I want to allow the non-root user to shutdown or reboot without having to use su, sudo or doas. I read a few article that suggested changing ownership of those commands to a group that user is part off, as well as changing some of the files permissions to allow the group to read and execute as root. When I tried following their directions I was able to change the group but not the permissions. Is it possible to change the permissions and if so how?
~# addgroup power
~# adduser $USER power
~# chown -R root:power /sbin/poweroff /sbin/reboot
~# ls -l /sbin/poweroff /sbin/reboot
lrwxrwxrwx 1 root power $DATE $TIME /sbin/poweroff -> /bin/busybox
lrwxrwxrwx 1 root power $DATE $TIME /sbin/reboot -> /bin/busybox
~# chmod -R 750 /sbin/poweroff /sdbin/reboot
~# ls -l /sbin/poweroff /sbin/reboot
lrwxrwxrwx 1 root power $DATE $TIME /sbin/poweroff -> /bin/busybox
lrwxrwxrwx 1 root power $DATE $TIME /sbin/reboot -> /bin/busybox
~# chmod -R u+S /sbin/poweroff /sdbin/reboot
~# ls -l /sbin/poweroff /sbin/reboot
lrwxrwxrwx 1 root power $DATE $TIME /sbin/poweroff -> /bin/busybox
lrwxrwxrwx 1 root power $DATE $TIME /sbin/reboot -> /bin/busybox
