Where to set transparent_huge_page during boot?
When starting mongo a warning is issued that
WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.
We suggest setting it to 'never'I read that this can be set using
echo never > /sys/kernel/mm/transparent_hugepage/enabledIf set manually, it is reset after a reboot. Where can I set this so that this setting is persistent?

I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do. (Gune | Titan A.E.)

I've read the info on sysctl, but I'm not sure what I should change. Can you give me another hint

Re: Where to set transparent_huge_page during boot?
You can't disable transparent_hugepages using sysctl, since the options just not there... so you'll have to add the boot parameter 'transparent_hugepage=never' to your bootloader's config file.
