</I>&gt;<i> &gt;&gt;&gt;&gt; This package, when installed will add a new menu option to your
</I>&gt;<i> &gt;&gt;&gt;&gt; bootloader. Simply install this package, reboot, select the &quot;Mageia 3

</I>&gt;<i> &gt;&gt;&gt;&gt; then perform a urpmi upgrade as you would normally.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; I've not specifically tested the upgrade part, only the installation
</I>&gt;<i> &gt;&gt;&gt;&gt; and creation of the initrd and bootloader entries in grub. I've also
</I>&gt;<i> &gt;&gt;&gt;&gt; not done this on an mga2 machine yet but will do soon enough.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; I just wanted to get this package &quot;out there&quot; for anyone wanting to
</I>&gt;<i> &gt;&gt;&gt;&gt; update their mga2 machines to mga3 a3 but not wanting to use the
</I>&gt;<i> &gt;&gt;&gt;&gt; installer.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; At present there are a few limitations:
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; 1. It requires kernel 3.3.8-2.mga2 to be installed (any flavour should
</I>&gt;<i> &gt;&gt;&gt;&gt; work). A specific kernel version is not really 100% necessary but it
</I>&gt;<i> &gt;&gt;&gt;&gt; does mean I can add hard requires to the package. This is only
</I>&gt;<i> &gt;&gt;&gt;&gt; desirable to prevent the situation where users install this upgrade
</I>&gt;<i> &gt;&gt;&gt;&gt; package but do not run it and later remove the kernel used to
</I>&gt;<i> &gt;&gt;&gt;&gt; generate the initrd for the bootloader menu item, thus breaking it.
</I>&gt;<i> &gt;&gt;&gt;&gt; Any smarter ideas on how to manage this welcome.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; 2. If you have /usr in a separate partition and have it mounted ro in
</I>&gt;<i> &gt;&gt;&gt;&gt; your fstab, you will have to manually change the fstab to rw for the
</I>&gt;<i> &gt;&gt;&gt;&gt; upgrade boot.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; Happy testing. Let me know if it kills any kittens. Please keep a
</I>&gt;<i> &gt;&gt;&gt;&gt; backup etc. etc.
</I>&gt;<i> &gt;&gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt;&gt; Col
</I>&gt;<i> &gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt; Thanks Colin.
</I>&gt;<i> &gt;&gt;&gt; The conversion works. But then the problem shows, we have no network.
</I>&gt;<i> &gt;&gt;&gt; doing a urpmi --download-all --auto-update only downloads the fist 120+
</I>&gt;<i> &gt;&gt;&gt; rpms (the ones needed before restart-urpmi
</I>&gt;<i> &gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt; What is needed is to add some directories and then the network will
</I>&gt;<i> &gt;&gt;&gt; start /var/run/netreport
</I>&gt;<i> &gt;&gt;&gt; /var/lock/subsystem/network
</I>&gt;<i> &gt;&gt;&gt; 
</I>&gt;<i> &gt;&gt;&gt; I will check after the upgrade if they can be deleted
</I>&gt;<i> &gt;&gt; 
</I>&gt;<i> &gt;&gt; Hmm, yes, I guess after doing the upgrade the various /var/run and
</I>&gt;<i> &gt;&gt; /var/lock folders would be nuked. In mga3 they will be created by
</I>&gt;<i> &gt;&gt; tmpfiles but not with a simple reboot on mga2...
</I>&gt;<i> &gt;&gt; 
</I>&gt;<i> &gt;&gt; Hmm, I wonder how best to do this... perhaps we could ship updated
</I>&gt;<i> &gt;&gt; packages for each of the packages which absolutely *need* this to do the
</I>&gt;<i> &gt;&gt; download... or perhaps we could just ship some essential config tweaks
</I>&gt;<i> &gt;&gt; in the this mageia-prepare-upgrade file. It shouldn't do any harm to do
</I>&gt;<i> &gt;&gt; the latter and it's a bit easier on the QA folk.
</I>&gt;<i> &gt; 
</I>&gt;<i> &gt; Humm we could just package mageia-prepare-upgrade in mga3 and add
</I>&gt;<i> &gt; it to urpmi priority list.
</I>&gt;<i> &gt; Thus it would also work for people who never apply updates...
</I>&gt;<i> &gt; My 2 cents
</I>&gt;<i> 
</I>&gt;<i> Not sure it would help. I mean users have to install it, reboot and then
</I>&gt;<i> install the rest...
</I>&gt;<i> 
</I>&gt;<i> Also how does the urpmi priority list work? Does that not require that
</I>&gt;<i> we install urpmi first? If so that likely won't work as there is a
</I>&gt;<i> chicken and egg scenario that prevents the rpm+urpmi from mga3 being
</I>&gt;<i> installed until the fs is updated.
</I>&gt;<i> 
</I>&gt;<i> 
</I>&gt;<i> Basically, a fully up-to-date mga2 (including rpm package and the
</I>&gt;<i> mageia-prepare-upgrade package) + reboot for preparation is needed for a
</I>&gt;<i> urpmi-based upgrades to work.
</I>&gt;<i> 
</I>&gt;<i> Col
</I>
OK, I started all over again from a completed mga 2 with all updates.
The requires are: Pizza and beer
install mageia-prepare-upgrade
change sources to cauldron
reboot with mageia-prepare-ugrade

eat pizza and drink beer, it takes a lot of time to pass all the time-outs

(it will boot into a none graphic shell)
login as root ans then startx
 create /var/run and then start the network
after network runs, remove the /var/run (otherwise filesystem will not install)

then use urpmi --auto-update

( got the message &quot;/&quot;  is mount read-only a few times and had to re-boot and go throught the 
/var/run cycle as desribed above)

This got me a full up-to-date cauldron
