 I keep a "permanent" SD card in each of my XOs.  In addition to
 "offloading" executables and data, my SD card provides file
 '/security/developer.sig' so that non-signed builds should boot even when
 'copy-nand' has wiped out the existing /security/develop.sig on NAND.

 Found out that OFW does not recognize '/security/develop.sig' on a
 removable storage device (i.e., SD card) if that file is on a partition
 (on the device) other than the first actual partition to be found in that
 device's partition table.  It was quite difficult to figure out why
 booting had failed (with a sad face) when the output (with 'check'
 pressed) given by Q2E33 OFW was:
 {{{
 Trying nand:security,\develop sig
 NAND: No such partition
 Trying nand:\security\develop.sig
 Trying nand:\boot\bootfw.zip
 Trying nand:\boot\runos.zip
 Boot failed
 }}}
 This despite a correct '/security/develop.sig' on /dev/mmcblk0p2.

 I even got the same failure (including those messages) after putting
 '/security/develop.sig' on an USB stick, booting with that stick inserted,
 __copying__ develop.sig to /security on NAND, and afterwards trying reboot
 without using the USB stick.  [In other words, failing to access
 /security/develop.sig in the first partition listed in the SD card's
 partition table - confused OFW enough that it *also* failed to access
 /security/develop.sig in NAND.]

 ----

 BTW -- every partition on every removable storage device which has a
 partition type of 0x82 or 0x83 causes OFW messages:
 {{{
 Error: Unknown file system
 Can't open disk label package
 }}}
