+Subject: [PATCH] setup-disk: fix running update-extlinux in chroot
+
+When installling the packages in new root, the update-extlinux trigger
+script will be executed. We make sure this does not fail by:
+ - run extlinux --install before we install packages
+ - mount /dev and /proc for the chroot
+ - temprorary disable grsecurity's chroot_caps
