dtfs memsets all allocated block content to 0 immediately, so to
...
avoid wasting unbelievable amounts of memory, set the blocksize to
something more believable. Should fix the memset-part to act only
up to the size the file is extended to, though.

Adapt to changes with mounting file systems.
...
Introduce a parameter -r to control the root node type. For example
"dtfs -r 'lnk /etc' /puffs" mounts dtfs with the root node as a
symbolic link to /etc:
jojonaru# ./dtfs -r 'lnk /etc' /puffs
jojonaru# ls -l /puffs
lrw-rw-rw- 1 root wheel 4 May 17 14:06 /puffs -> /etc
jojonaru# cd /puffs
jojonaru# pwd
/etc
jojonaru#
Extra credit for figuring out how to unmount this file system with
umount(8).
Likewise, "dtfs -r 'chr 2 12' /puffs" makes /puffs (i386) /dev/zero etcetc.
