Thank you.

Looks like the feature is only supported by particular file systems.  I 
don't see anything at mkfs(8), but I do (for example) see the -m flag at 
mke2fs(8).

What I've done in the past is to make the boot partition big enough for 
emergency, super-user system administration.  In the default boot 
configuration, I just don't mount /boot.  When the other partitions get 
filled up by some runaway process (which happens with surprising (to me) 
frequency), I mount the boot partition so I have some breathing room.  I 
guess the formally reserved blocks in the filesystem are meant to serve 
the same purpose.
