Bonjour,
I sent several messages about kernel updates and grubby.
Once upon a time I made 4 partitions on a ssd drive where the system is installed. I use raid1+lvm
on sda1 and sdb1 I put the a /boot partition (raid1) for a debian install on sda3 and sdb3 I also put /boot partition (raid1) for a fedora install
on sda2 and sdb2 I put a / partition (raid1+lvm) with label "debian-racine" (at that time I had a debian install) on sda4 and sdb4 I put a / partition (raid1+lvm) with label "fedora-racine" for a fedora install.
So I had two linux installs: one was debian the other was fedora.
I abandonned debian and used the debian partition to install a fedora version. I wanted to keep two different partitions: on one partition fedora-n on the other fedora-(n+1).
Then appears the "dnf system upgrade" and I disabled the my sda3-sda4 partitions and only used sda1-sda2 partitions (with label "debian-racine") for my system.
Everything was ok untill grubby replaced grub2-mkconfig: when there is a kernel update, grubby uses the disabled sda3-sda4 partitions as the / parttion in the /boot/grub2/grub.cfg file.
I have now destroyed these partitions but grubby still uses them and writes a faulty /boot/grub2/grub.cfg file.
Where does it find that these partitions still exist?
I can't upgrade my system now because I fear that the boot config file will refer to a partition wich no longer exists on my system.
Please help me!
