[Mageia-dev] WARNING to users with LVM drives.

When you do the latest round of Cauldron updates, you will be using a
new version of systemd that now uses udev information to detect when LVM
volumes are ready.

In the past with mkinitrd this information was never available due to
the fact that LVM volumes were activated before udev started and thus
appropriate change events could never be fired. We are now recommending
the use of dracut over mkinitrd. Therefore, you should see the previous
mail on this list about installing and testing dracut (you just need to
install it and regenerate your initrd).

If you find yourself with a system that is unable to boot, do not fret.

You should be prompted to enter your root password to enter an emergency
shell (you may have to press ESC to get rid of Plymouth graphics to see it).

Once you enter your root password (the rootfs will still be mounted OK),
then just manually call "mount /foo" for each partition you have on LVM
(the commands should all work) and then type: "systemctl start

Nothing here is fatal, but you need to be armed with info so as not to
get stuck!
