From 8b680b00d49bdd1064918ffd221ffbcc11ba902a Mon Sep 17 00:00:00 2001 From: Pavel Shlyak Date: Thu, 26 May 2022 21:00:51 +0300 Subject: image: Add fat32 support. * gnu/build/image.scm (make-vfat-image): Pass fs-bits as an argument and force 1kb logical sector size only if "ESP" flag is set. (make-partition-image): Add "fat32" partition type, support explicit "fat16" type with vfat alias. * gnu/system/image.scm (partition->dos-type partition): Return file system IDs for "fat16" and "fat32" partitions. (partition->gpt-type partition): Ditto.
