How to upgrade from Fedora29 to Fedora30 with less stress.

Let's do "By the book" instructions:

Update software and back up your system.
dnf upgrade --refresh

Install the DNF plugin.
dnf install dnf-plugin-system-upgrade

Start the update with DNF.
dnf system-upgrade download --releasever=30

Reboot and upgrade.
dnf system-upgrade reboot

Fails, fall into dracut, does not recognize LVM name changes.
This bug has not yet been fixed!
Bug 1597034 - Changed volume group name not taken in account
Reset to reboot, at grub - edit line and replace fedora_localhost-live with correct volume name.
Then edit /etc/default/grub
What did they change in Fedora30?
Boot Loader Specification
So, to change the VLM name:
1) vgrename -v fedora_localhost-live fedora
2) edit fstab
3) was to edit grub.cfg now instead edit grubenv and /etc/default/grub
4) mkinitrd -f -v /boot/initramfs-$(uname -r).img $(uname -r)
reboot the system and check at grub for the new name.

Now let's fix the problems.
In order to bypass renaming of eth0 and eth1 to some obscure name:
In the ifcfg-eth? files, define device=eth?

Instead of watching the boot process, I get the fedora lemon!
Again edit grubenv or /etc/default/grub and replace "rhgb quiet" with "rhgb video=VGA-1:1920x1200 LANG=en_US.UTF-8 verbose loglevel=KERN_NOTICE"
must resolve all .rpmnew and .rpmsave files rpmconf -a

must run hp-setup again to detect scanner
hp-setup -i 192.168.90.10

Terminal and Nautilis Menu Bar needs color
To file /home/.config/gtk-3.0 Add:
.titlebar:not(headerbar) {
background-image: none;
background-color: @theme_bg_color;
}

Fedora install no longer asks for root password.
To change the root password type:
sudo passwd root

Seems they fixed the problem with the Activities Menu reappearing between Applications and Places, and thereby disabling those menus. This was a Fedora 27 bug!
Workaround: Alt-F2 then "r" enter everytime it happens.
