Every time I see one of these guides I'm surprised how many different ways there are to persist the governor state.

Insanity I tell you. We need to develop one universal standard that covers everyone's uses cases.

I prefer using cpupower and cron jobs :)

Solid list. Two more for a ZFS-based box: cap zfs_arc_max explicitly if idle RAM usage matters, ZFS will happily eat most of your RAM for ARC and won't always release it cleanly, keeping memory controllers busier than needed at idle. And check hdparm -B / hd-idle for spinning drives not in constant use, letting them actually spin down makes a bigger power dent than people expect.

Spindown and spinup unfortunately have wear on the drives and ever since I killed a bunch of desktop WD green drives that way back in the day, I'm too scared to reenable this on my (now 100TB+) NAS.
