danmcdIt's something you want in /etc/system but to get that you need loader.conf.local additions.
-
danmcdSee piadm(8) along with here: docs.smartos.org/modifying-boot-files
-
danmcdYou wanna add $BOOTPOOL/boot/custom/loader.conf.local and make sure you deactivate/reactivate the PI in question.
-
danmcdSee system(5) too.
-
danmcdIt's not runtime-tunable from what I can tell like some other kernel tunables. You have to set it up via /etc/system.
-
pjusticeEr, yeah, I think I more or less understand how to do it at boot. I was hoping for a one-shot test method before rebooting.
-
pjusticeAh well.
-
pjusticeThanks, dancmd
-
pjusticeer, danmcd
