Okay, ext4 support in snapper is still experimental one and it needs patched kernel + special version of e2fsprogs (available in only SUSE/openSUSE?) Now I would specify --disable-ext4 option since Debian doesn't have such kernel/e2fsprogs and saying "ext4 support" confuses normal users. > > /usr/lib/x86_64-linux-gnu/libsnapper.so.4.1.0 contains chattr.
