$deb/grub.cfg is currently a symlink to $rhel/grub.cfg. Your provider

configuration, boot entries, and modules in a different location from
where your operating system stores this data. In order to allow the

current $deb directory, re-create $deb as a symlink to $rhel,

Disabling the BLS boot entry format prevents the resulting system from
adding kernel updates to any boot loader configuration, because the old
utility responsible for maintaining native GRUB2 boot loader entries was
removed and replaced with a wrapper around the new utility, which only
understands BLS format. This means that the old kernel will be used on
reboot, unless the GRUB2 configuration file is manually edited to load the
new kernel. Furthermore, after a few kernel updates, the DNF package
manager may begin to remove old kernels, including the one still used in
the configuration file. If that happens, the system will fail to come back
after a subsequent reboot.
The safe option is to remove the following line in /etc/default/grub:
GRUB_ENABLE_BLSCFG=false
or to change it so that it is set to "true" instead.
