Thanks for your much appreciated work!

Is it not simpler/enough to replace all these commands with:

# cd /usr/src
# fetch http://people.freebsd.org/~pjd/patches/zfs_20061117.patch.bz2
# bzip2 -d zfs_20061117.patch.bz2
# patch -p0 < zfs_20061117.patch

or even shorter:

# cd /usr/src
# fetch -o - \
  http://people.freebsd.org/~pjd/patches/zfs_20061117.patch.bz2 \
  | bunzip2 | patch -p0

?

The point is that using the '-p0' option we can avoid creating
directories manually.
