OK, I tried to post this last night but apparently kmail 3.2.0 decided I don't need to SEND email anymore. This lovely little rc.d script will create, newfs, and potentially chown and chmod md's for you, just early enough in the boot process you can put the md devices in fstab and mount them just like any other filesystem. This is configured from /etc/rc.conf, as in: ramdisk_units="10 11 12" ramdisk_10_config="-t swap -s 128m" ramdisk_10_owner="wes:staff" ramdisk_10_perms="1755" ramdisk_11_config="-t malloc -s 32m" ramdisk_11_newfs="-b 4096 -f 1024" This results in /dev/md10 (with ownership and permissions as specified) and /dev/md11 (with default ownership and permissions, 4K/1K block/frag size), but not a /dev/md12 as its type has not been specified.
