Package: vmdebootstrap Version: 1.5-1 Severity: normal Ohai,
as discussed with terceiro on IRC: when vmdebootstrap is executed on Stretch, it will use mkfs from Stretch which defaults to enabling metadata_csum. That, however, is not compatible with e2fsck from Jessie: /dev/vda1 has unsupported feature(s): metadata_csum e2fsck: Get a newer version of e2fsck! I think vmdebootstrap should default to creating the fs with "-O ^metadata_csum" when building <= Jessie.
