Remotely, I was following this discussion; I'm suprised by this solution
and I wonder how I ever would be able to find out myself about this misterious

I did 'apropos usermount', 'man sysctl' and 'man sysctl.conf', and all did not
give me any hint to the above vfs.usermount solution.
Also 'sysctl -ad | grep vfs.usermount' outputs no info.

Actually, I had this feeling with other answers on this list: 'set this-or-that
sysctl variable'. I never could find any info on my FreeBSD box, to help me
further understand.

What is this sysctl-black-magic about and where is more information?
