That's what I'm finding, there's some overlap but not enough that I can confidently administer the system yet. I've had the FreeBSD Handbook open in links for days 😅.
I'm starting to get the hang of things, there's a few things I wish there were analogs for on FreeBSD that I've used on Linux for modifying swappiness and other minutiae but I suppose eventually I'll know enough to be the change I wanna see in the world and just write the kernel extension to do it myself.
