'increased values' sysctl tweak in chapter 7 section 4 of handbook actually decreases values

[Ashlen]

I'm unsure if this is the right mailing list to send this to. I hope so.

Yet if I actually change them on 13.0-RELEASE, the values decrease, not increase.

$ priv sysctl kern.ipc.shmmax=67108864
kern.ipc.shmmax: 536870912 -> 67108864
$ priv sysctl kern.ipc.shmall=32768
kern.ipc.shmall: 131072 -> 32768

Perhaps this should be removed? I set up a FreeBSD HTPC today on the
amd64 architecture and it handles video fine without any adjustment.

Seems it was mentioned before, but never fixed.
