** Description changed:
- Binary package hint: casper
+ When upgrading a live USB stick, we use a diverted version of update-
+ initramfs installed by casper which arranges for /casper/vmlinuz and
+ /casper/initrd.lz at the top level of the CD to be updated.
+ Unfortunately this script does not quite operate correctly; it assumes
+ that there will be vmlinuz and initrd.gz links in the root directory,
+ when in fact they are often (although not exclusively) in /boot. It
+ needs to try both.
- As discussed with Colin, fix in hand.
+ DEVELOPMENT BRANCH: This has been addressed in casper 1.237 in maverick:
+
+ * Make the USB update-initramfs shim cope with vmlinuz and initrd.img
+ being in /boot rather than / (LP: #591207).
+
+ PATCH: http://bazaar.launchpad.net/~ubuntu-
+ branches/ubuntu/lucid/casper/lucid/revision/813
+
+ TEST CASE: Build a live USB stick of 10.04 (no need to install it
+ anywhere), and upgrade it to the current bits in lucid-updates (should
+ fail) and then from scratch to lucid-proposed (should succeed). There
+ are some other problems with this workflow so you may run into other
+ failures; for the purposes of this bug, the important thing is that
+ /casper/vmlinuz and /casper/initrd.img at the top level of the USB stick
+ should be updated with copies of the new /boot/vmlinuz and
+ /boot/initrd.img.
+
+ REGRESSION POTENTIAL: This diverted script can hardly get worse, given
+ that it generally isn't working at all right now.
