In one computer (Isengard), on /etc/default/grub I got:
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda2 splash=verbose showopts resume=/dev/disk/by-label/Swap splash=silent quiet showopts"
which I had to change back to the correct one:
GRUB_CMDLINE_LINUX_DEFAULT=" showopts resume=/dev/disk/by-label/Swap splash=verbose"
Why change that line at all, adding the same options (not
replacing) with unpredictable results?
On another computer (Minas-Tirith), I get a similar issue:
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-label/Swap splash=verbose console=tty1 loglevel=3 showopts resume=/dev/disk/by-label/Swap splash=silent quiet showopts"
It seems that what it thinks are the correct options are added to the end
of the line.
Correct line:
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-label/Swap splash=verbose console=tty1 loglevel=3 showopts"
On this computer I got a grub error during the update, of which I took a
photo; fortunately it did not impede reboot, but I have no idea what it
means.
Execution of command *[[*/usr/sbin/grub2-install* ... failed.
Exit code 1
Error output: Installing for i386-pc platform.
/usr/sbin/grub2-install: error: the drive hd0 is defined multiple times in
the device map /boot/grub2/device.map
Well, the file contains:
(hd0) /dev/sda
(hd0) /dev/sda
(hd1) /dev/sdb
This error I can find in the /var/log/YaST2/y2log-1.gz file:
