Hello
After upgrading to newest kernel on leap 15 (4.12.14-lp150.12.28-default) my system did not boot anymore.
The problem was that on old swap partition was deleted from disk sda,
The old value was still in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=“resume=/dev/disk/by-uuid/76739b26-064e-49ba-9495-11b5b981e0b6 splash=silent quiet showopts”
But I have already done a lot of upgrades which went right with new swap partition, so I really don’t know why this update
took values from /etc/default/grub instead from /boot/grub2/grub.cfg
I think grub2 should check if the partition in GRUB_CMDLINE_LINUX_DEFAULT is a valid swap partition or by installing each kernel stanza and print at least a warning if it does not exist…
Greetings
