From 742d6bf13e5bddc5e30edeb8b8c314f47cf97e4d Mon Sep 17 00:00:00 2001 From: Carlos Santos Date: Sun, 23 Apr 2017 00:49:13 +0200 Subject: [PATCH] e2fsprogs: refactor to fix conflicts with busybox and util-linux So far we attempted to solve the conflicts between busybox and e2fsprogs by removing busybox programs from /bin and /sbin, leaving the e2fsprogs ones at /usr/bin and /usr/sbin. This fails with BR2_ROOTFS_MERGED_USR=y, leading to situations like the one described in bug 9436. We could provide a better solution by means of a fine-grained selection of programs, like util-linux does, but this would require big changes in e2fsprogs. So instead of resorting to dirty tricks we switch to a more pragmatic approach: - Drop all configs to select/deselect utilities without corresponding enable/disable options to the configure script. In other words, we always install the basic set of utilities. - fsck has a configure option, so use it. Note that --enable-fsck is only about the wrapper, not about e2fsck. - Install e2fsprogs utilities at /bin and /sbin, overriding the ones eventually installed by busybox. - Let the e2fsprogs build system create the symlinks mkfs.ext2 -> mke2fs etc. fsck.ext4dev and mkfs.ext4dev were dropped in version 1.43.4. Notice that these changes do exactly the opposite of what is requested in bug 9436. On the other hand the policy for e2fsprogs becomes coherent with the one for util-linux: busybox never wins.
