So with help of Tomas Chvatal, I've got a list of packages that directly require e2fsprogs: autofs/autofs.spec clicfs/clicfs.spec cloud-init/cloud-init.spec cluster-glue/cluster-glue.spec dar/dar.spec dmapi/dmapi.spec docker/docker.spec dump/dump.spec ext4magic/ext4magic.spec fsarchiver/fsarchiver.spec gparted/gparted.spec installation-images-openSUSE/installation-images-openSUSE.spec jfsutils/jfsutils.spec kiwi/kiwi.spec lash/lash.spec libcacard/libcacard.spec libcacard/qemu-linux-user.spec libcacard/qemu.spec libcacard/qemu-testsuite.spec libguestfs/libguestfs.spec libvirt-cim/libvirt-cim.spec lighttpd/lighttpd.spec linuxrc/linuxrc.spec mc/mc.spec nfs-utils/nfs-utils.spec ocfs2-tools/ocfs2-tools.spec openhpi/openhpi.spec partclone/partclone.spec parted/parted.spec perl-Bootloader/perl-Bootloader.spec qemu/libcacard.spec qemu-linux-user/libcacard.spec qemu-linux-user/qemu-linux-user.spec qemu-linux-user/qemu.spec qemu-linux-user/qemu-testsuite.spec qemu/qemu-linux-user.spec qemu/qemu.spec qemu/qemu-testsuite.spec qemu-testsuite/libcacard.spec qemu-testsuite/qemu-linux-user.spec qemu-testsuite/qemu.spec qemu-testsuite/qemu-testsuite.spec quota/quota.spec reiserfs/reiserfs.spec samba/samba.spec sbd/sbd.spec snapper/snapper.spec star/star.spec storeBackup/storeBackup.spec virtualbox/virtualbox.spec xfsdump/xfsdump.spec Nothing here looks non-sensical however he also found out by grepping the final rpm dependency list that this is enough to make every package depend on e2fsprogs. So the suggestion he had was to add "BuildIgnore: e2fsprogs" to suse-module-tools. Would that be OK with you?
