Hello! I am not sure whether this issue has been fixed.
We're seeing this issue on buildds and porterboxes on Debian Ports, regenerating the chroots fails: dpkg: warning: ignoring pre-dependency problem! Preparing to unpack .../tar_1.34+dfsg-1.2_ppc64.deb ... Unpacking tar (1.34+dfsg-1.2) ... Selecting previously unselected package usr-is-merged.

Could it be that debootstrap needs to be switched to enabled usrmerge by default? Adrian -- .''`.
