syslinux: process @rescue_hash@ (forensic mode) This value is used to authenticate rescue rootfs image by verifying the squashfs file's sha256sum before use (propagator-20140419+). Looks like this check might be useful for other stage2 images as well but let's get started with this one. Thanks Maxim Suhanov <suhanov/group-ib.ru> for both http://www.forensicswiki.org/wiki/Forensic_Live_CD_issues and propagator patches. 2014-04-18 13:26:15 +04:00			`#!/bin/sh`

syslinux: fixed for using BOOTLOADER not equal syslinux Do not create syslinux.cfg if EFI_BOOTLOADER is set to not equal grub-efi. 2020-01-06 19:26:52 +03:00			`[ -d "syslinux" ] \|\| exit 0`
