Tags: patch
Configuring the packet gives:
E: cannot access "/dev/root": No such device
dpkg: error processing package syslinux-stuff (--configure):
subprocess installed post-installation script returned error exit status 1
This is because in syslinux-stuff.postinst the following will be called:
extlinux-install /dev/root
The kernel is started with this cmdline (no modules, no initrd):
root=/dev/sda1 ro rootfstype=ext4 BOOT_IMAGE=/boot/vmlinuz-3.15.1
# findmnt -n --raw -c -o SOURCE /
/dev/root
# ls -l /dev/root
ls: cannot access /dev/root: No such file or directory
# cat /proc/mounts | awk '{ print $1 " " $2 }' | grep /$
rootfs /
/dev/root /
The attached patch solves the problem.
