[sbuild](https://wiki.debian.org/sbuild) is a wrapper script around `schroot`.

```{note}
A newer backend, `unshare`, can be used for `sbuild` in place of `schroot`. Compared to `schroot`, it does not need chroot configuration and does not need to run the build as root.

To use `unshare`:

* Install the {pkg}`mmdebstrap` and {pkg}`uidmap` packages.

* Add the following to your `sbuild` configuration in {file}`~/.sbuildrc`:

```none
$chroot_mode = "unshare";
$unshare_mmdebstrap_keep_tarball = 1;
```

Note that while Debian has transitioned to `unshare`, it is not used by Launchpad builders, so it may fail to build some packages.
```

In these examples, replace `my_user` with your own username.
