Re: how to create grub rescue kernel entry?
Correction, it should be "grub2-mkconfig -o /boot/grub2/grub.cfg" (not grub.conf). -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org

Assuming that you installed required dracut support and you do not have 'dracut_rescue_image="no"' in your dracut configuration. This actually worked wherever I tried.

how to create grub rescue kernel entry?
The F24 lives don't contain a rescue kernel or generate the corresponding grub entry (see https://bugzilla.redhat.com/show_bug.cgi?id=1317709 ). Is there a way to install the rescue kernel if it was not done during the initial install? (The package dracut-config-rescue was not installed, and I've installed that manually.) I've nominated this bug as a FE, but it would be less important if there's a way to fix the problem after install. -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org

I removed the entry from my grub2-efi.cfg and it never came back until I realized that I hadn't removed the rescue stuff from /boot. if you have an old rescue kernel and initramfs it won't make a new one. Removing those and installing a new kernel did make it work. So, to cleanly remove it: * remove the grub2* entry * rm the stuff from /boot * dnf remove dracut-config-rescue kevin pgpj8fBbKIIBe.pgp Description: OpenPGP digital signature -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org

I remember that ask have this question and the answer. /etc/kernel/postinst.d/51-dracut-rescue-postinst.sh $(uname -r) /boot/vmlinuz-$(uname -r) works for me in F23 . after google it: "how to create grub rescue site:ask.fedoraproject.org"best reference is : https://ask.fedoraproject.org/en/question/40409/cant-boot-into-rescue-m ode-how-to-re-generate-initramfs/ Best regards, -- Sérgio M.

> /etc/kernel/postinst.d/51-dracut-rescue-postinst.sh $(uname -r) > /boot/vmlinuz-$(uname -r) Thanks. I ran this command in F24 and it created the rescue mode files in /boot. Looking at /boot/grub2/grub.conf indicated that the rescue mode grub entry was the first on the list, so I ran "grub2-mkconfig -o /boot/grub2/grub.conf" manually and it put the rescue mode entry in the proper location (after all the non-rescue kernels). -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org
Re: how to create grub rescue kernel entry?
When I used this method to create new rescue mode files for my F23 box (which already had a rescue mode entry), I got an additional rescue mode entry at the top of the grub menu. This was fixed by manually editing /boot/grub2/grub.conf to delete the new entry (as mentioned in https://ask.fedoraproject.org/en/question/40409/cant-boot-into-rescue-mode-how-to-re-generate-initramfs/ ). -- test mailing list test@lists.fedoraproject.org To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@lists.fedoraproject.org
