change filesystem for /dev/md/dsk/d5 from raid5 to striped

Done:

    Filesystem            kbytes    used   avail capacity  Mounted on
    /dev/md/dsk/d5       19584720    9536 19269332     1%    /ftp-root
    /dev/md/dsk/d6       15667560    6120 15172028     1%    /lxr-root

d5 (/ftp-root) is a raid5 volume; it is "reliable" but slow.

d6 (/lxr-root) is a simple stripe volume.  It is fast but not safe; if even
a single disk crashes, you will lose all the data on it.

Both volumes have vxfs filesystems with delayed log commits for
performance; in the case of the ftp volume it should not be written often
and in the case of lxr, it's probably not important if you lose the tail
end of the log after a crash anyway.

I strongly recommend setting up a jail for the anonymous ftp area, similar
to what we did for cvs.  I've extended the jailsh frob we use for mirroring
via rsync a bit so that you can specify the root on the command line (and
improved the syslogging a little bit).  I'll check it in tomorrow.
