Add kernel post-installation script to regenerate grub2 config Since we now allow using Fedora kernel, add a script to generate proper bootloader configuration then. Standard Fedora mechanism relies on Boot Loader Specification support in grub2, which sadly does not support Xen, so it is useless in Qubes. 2015-07-10 15:54:24 +00:00			`#!/bin/sh`

Generate initramfs in kernel-install hook The default one generates initramfs in location expected by Boot Loader Specification, which as noted before, isn't useful for Qubes. 2015-07-11 12:20:04 +00:00			`COMMAND="$1"`

kernel-install: avoid creating initramfs multiple times There are multiple places where initramfs can be created: - /boot/iniramfs-.img - /boot/$MACHINE_ID/.../initrd (unused on Qubes, but created by Fedora scripts) - /boot/efi/EFI/.../initramfs-.img Do not generate all of those from scratch, but try to reuse existing image (if exists). Since one dracut call may last even 5 minutes, this change should greatly reduce installation time. Fixes QubesOS/qubes-issues#3637 2018-02-27 22:19:50 +00:00			`BOOT_DIR_ABS="$3"`
