since it makes a fairly decent template for fdisk -i.  Change the procedure
that makes the rb600 installation miniroot image to use fdisk -i instead of
dd(1) to create the MBR for the image.  Adjust the miniroot disk type in
/etc/disktab to the slightly different layout that fdisk -i creates.

only the ramdisk entry and a new entry for building rb600 installation
miniroot images.

*concatenate* to the file -- not replace it -- since the installer is going
to be using this file itself.

yeah sure deraadt@

var/db/sysmerge/etcsum is created after the cksum calls and etcsum is
part of the etc set).

arc4random() is slow, but it induces getpid() calls; also saves a
bit on stirring efforts

doesn't test it, so factor out the two places that test it into a
routine and do the refreshing there.  With this, arch4random_buf()
doesn't trigger superfluous calls to getpid() when filling large
buffers.
