</I>><i> You should see several packages now that you cannot install on Cauldron.
</I>><i> This is intended behaviour.
</I>><i>
</I>><i> Here is how to update your cauldron systems:
</I>><i>
</I>><i> 1. Run "urpmi --auto-update" install everything that can be installed.
</I>><i> 2. Ensure that latest dracut is installed. Run "urpmi dracut" to make
</I>><i> sure (it may have been excluded in the --auto-update if it was in a
</I>><i> transaction with other packages that could not be installed).
</I>><i> 3. Ensure that you do not have zapata or dpkg installed (rpm -e zapata;
</I>><i> rpm -e dpkg)
</I>><i> 4. Generate a new initrd and include the conversion script: dracut -f
</I>><i> -a convertfs
</I>><i> 5. If you have /usr on a separate partition
</I>><i> - Ensure there is enough free space to hold /bin, /sbin, /lib and
</I>><i> /lib64 content.
</I>><i> - If your /usr is mounted readonly, change your /etc/fstab to mount
</I>><i> it rw.
</I>><i> 6. Reboot.
</I>><i> 7. At the bootloader prompt, edit the command line and append: "rw
</I>><i> rd.convertfs" (without the quotes) to your command line and then boot.
</I>An other way for this step is to edit /boot/grub/menu.lst and change the
line for the first kernel by adding "rw rd.convertfs" (without the
quotes) and removing "splash quiet" (optionnal)
After the reboot (and the /usr conversion), you need to rollback your
changes.
><i>
</I>><i> That should be all that is needed :)
</I>><i>
</I>><i> If you are extra paranoid, or want to see what is going on, then you can
</I>><i> remove the "splash" and "quiet" options from the kernel too.
</I>><i>
</I>><i> If you want to see things in more depth, you can also add
</I>><i> rd.break=pre-pivot to the kernel. You will be dumped into a shell with
</I>><i> your / mounted as /sysroot. This shell is *before* conversion. If you
</I>><i> type "exit" the conversion will be done, and you'll be dumped to another
</I>><i> shell afterwards. Typing exit once more here will boot the system as normal.
</I>><i>
</I>><i>
</I>><i>
</I>><i> All the best and good luck!!!
</I>><i>
</I>><i> Col
</I>><i>
