Agreed, on some systems I actually do mkfs on boot for temporary cache partitions. Not just to clean it out, but to make it more robust -- the oft-changed SQUID cache is the most likely partition to go unfixably south if someone pulls the power for whatever reason.

mkfs.reiser4
mkfs.reiser4(8) reiser4progs manual mkfs.reiser4(8)
NAME
mkfs.reiser4 - the program for creating reiser4 filesystem.
SYNOPSIS
mkfs.reiser4 [ options ] FILE1 FILE2 ... [ size[K|M|G] ]
DESCRIPTION
mkfs.reiser4 is reiser4 filesystem creation program. It is based on new libreiser4 library. Since libreiser4 is fully plugin-based, we have
the potential to create not just reiser4 partitions, but any filesystem or database format, which is based on balanced trees.
COMMON OPTIONS
-V, --version
prints program version.
-?, -h, --help
prints program help.
-y, --yes
assumes an answer 'yes' to all questions.
-f, --force
forces mkfs to use whole disk, not block device or mounted partition.
MKFS OPTIONS
-b, --block-size N
block size to be used (architecture page size by default)
-L, --label LABEL
volume label to be used
-U, --uuid UUID
universally unique identifier to be used
-s, --lost-found
forces mkfs to create lost+found directory.
PLUGIN OPTIONS
-p, --print-profile
prints the plugin profile. This is the set of default plugins used for all parts of a filesystem -- format, nodes, files, directo-
ries, hashes, etc. If --override is specified, then prints modified plugins.
-l, --print-plugins
prints all plugins libreiser4 know about.
-o, --override TYPE=PLUGIN, ...
overrides the default plugin of the type "TYPE" by the plugin "PLUGIN" in the plugin profile.
Examples:
assign short key plugin to "key" field in order to create filesystem with short keys policy:
mkfs.reiser4 -yf -o key=key_short /dev/hda2
