[Bug 2087937] Re: [MIR] mmdebstrap

[Lukas Märdian]

ACK. Feel free to file a proper MIR for mmdebstrap (re-using this bug
report), remember to provide a good rational about the duplicated
mmdebstrap vs debootstrap and potentially a migration plan for demoting
debootstrap eventually.

Title:
  [MIR] mmdebstrap

Status in mmdebstrap package in Ubuntu:
  Incomplete
Status in sbuild package in Ubuntu:
  Fix Released

Bug description:
  sbuild 0.87.0 grew a new Recommends on mmdebstrap, which is not in
  Ubuntu "main".

  It allows for (optionally) running sbuild in "unshare" mode, to
  automatically create chroot tarballs. We should probably downgrade
  this new Recommends to a suggests, in order to avoid a component-
  mismatch (in Ubuntu) and allow sbuild to migrate. People who want to
  use the "unshare" feature need to "apt install mmdebstrap" manually.

  sbuild (0.87.0) unstable; urgency=medium

    [ Johannes Schauer Marin Rodrigues ]
    * If a tarball can't be found, create a chroot on-demand using mmdebstrap.
      This version introduces an experimental new feature for the unshare
      backend which is supposed to make sbuild more easy to use because sbuild
      will manage the chroot tarballs itself.  With unshare-mode, sbuild will
      now automatically create a chroot tarball upon startup using mmdebstrap
      if it cannot find one in ~/.cache/sbuild.  This feature can be disabled
      by setting $unshare_mmdebstrap_auto_create=0; in your ~/.sbuildrc. If
      you like the feature and you would like to keep the tarballs sbuild
      creates so that they can be re-used in subsequent invocations of sbuild,
      you can set $unshare_mmdebstrap_keep_tarball=1; in your ~/.sbuildrc.
      This will also make sbuild update an existing tarball (by re-creating
      it) if it has become too old. The maximum age of a chroot tarball can be
      specified by setting $unshare_mmdebstrap_max_age to a maximum age value
      in seconds (default is 604800, which is one week). To customize the
      chroot tarball creation, refer to the setting
      UNSHARE_MMDEBSTRAP_EXTRA_ARGS in your sbuild.conf(5).

    * Use empty release in unshare autopkgtest (Closes: #1085450)
