I think this is a good idea, and it would also avoid upgrade problems such as https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1667512 in the case of things like stuck NFS mounts. To avoid backport surprises, I would suggest adding a dependency on coreutils (>= 8.24), which introduced the feature of sync(1) being used here. I've put all this in a merge request: https://salsa.debian.org/kernel-team/initramfs-tools/merge_requests/6 -- Colin Watson [cjwat...@debian.org]
