guix.git/gnu/packages/patches/mtools-mformat-uninitialized.patch, branch master Personal branch of https://git.savannah.gnu.org/cgit/guix.git/ for implementing 'guix deploy'. https://git.jakob.space/guix.git/atom?h=master 2019-04-20T22:51:19Z gnu: mtools: 'mformat' initializes boot sector before writing it. 2019-04-20T22:51:19Z Ludovic Courtès ludo@gnu.org 2019-04-20T22:46:44Z urn:sha1:1b0b1651b16bd67fa5a583cfe6ce98ac9df80e56 This is the last bit fixing <https://bugs.gnu.org/35283>. Previously, 'mformat' (used by 'grub-mkrescue') would pass uninitialized bytes to write(2), leading to non-deterministic FAT image contents. This patch fixes that. * gnu/packages/patches/mtools-mformat-uninitialized.patch: New file. * gnu/packages/mtools.scm (mtools)[source]: Use it. * gnu/local.mk (dist_patch_DATA): Add it.
