rescue kernel

[Patrick Dupre]

Hello,

In the past I could regenerate a rescue kernel by using
/etc/kernel/postinst.d/51-dracut-rescue-postinst.sh

But now, this script does not exist any more
What is the alternative to restore the /boot/*rescue* files?

Thank

Run
/usr/lib/kernel/install.d/51-dracut-rescue.install add $(uname -r) "" /lib/modules/$(uname -r)/vmlinuz
in boot, and it will create a rescue kernel from the currently running
kernel.

Do I really need to get this *rescue* files ?
grub complains, and I cannot boot on the last kernel.

You don't need it.  If you're referring to the rescue entry, then if the 
files don't exist, the entry obviously won't work.  If you don't want 
that entry, then find the file in /boot/loader/entries that refers to it 
and delete that file.

But also, if the rescue files are deleted, they should get automatically 
re-created at the next kernel install.
