OK, so the packages have now all been uploaded.
You should see several packages now that you cannot install on Cauldron.
This is intended behaviour.
Here is how to update your cauldron systems:
1. Run "urpmi --auto-update" install everything that can be installed.
2. Ensure that latest dracut is installed. Run "urpmi dracut" to make
sure (it may have been excluded in the --auto-update if it was in a
transaction with other packages that could not be installed).
3. Ensure that you do not have zapata or dpkg installed (rpm -e zapata;
rpm -e dpkg)
4. Generate a new initrd and include the conversion script: dracut -f
-a convertfs
5. If you have /usr on a separate partition
- Ensure there is enough free space to hold /bin, /sbin, /lib and
/lib64 content.
- If your /usr is mounted readonly, change your /etc/fstab to mount
it rw.
6. Reboot.
7. At the bootloader prompt, edit the command line and append: "rw
rd.convertfs" (without the quotes) to your command line and then boot.
That should be all that is needed :)
How to update a chroot?
Answering to myself:
chroot $chroot urpmi dracut
$chroot/usr/lib/dracut/modules.d/30convertfs/convertfs.sh $chroot
That did the conversion, but I still can't update, probably because my
rpm is too old (rpm-4.9.1.3-2.mga2) as it was not possible to update
it before the conversion (it pulls filesystem).
Yeah in this case if the conversion is done, I'd just recommend
installing filesystem --nodeps and the rest should flow. It's not ideal
certainly, but there is still time to polish this a bit before upgraders
get hit by this (and as there will be updated rpm packages in the stable
releases, it should mitigate this specific problem, but we should still
see if we can do things better)
Polish this a bit? It is not at all ready, and as I said earlier rpmlib is
broken. Please don't upload broken rpm packages to stable releases.
Maybe the instructions should be:
- install dracut and kernel-desktop-latest from mga3
- reboot, make sure the "usrmove filesystem update"
kernel entry is chosen in the bootloader
- upgrade to mga3 as usual
But that means a lot of things are still missing:
- dracut automatically including the conversion script
(only when needed?)
- automatic generation of the bootloader entry mentioned above
- removal of this bootloader entry after conversion
