dh_testroot — ensure that a package is built with necessary level of root permissions
dh_testroot [debhelper options]
dh_testroot is used to determine if the package has access to at least the level of root access that it declared it needed via the Rules-Requires-Root (R³) field.
The following is how dh_testroot behaves based on the effective value of the R³ field:
dh_testroot asserts that it is run as root or under fakeroot(1).
dh_testroot returns successfully.
- Any other value than the above
dh_testroot asserts that it is either run as root (or under fakeroot(1)) or the builder has provided the DEB_GAIN_ROOT_CMD environment variable (e.g. via dpkg-buildpackage -r).
For backwards compatibility, dh_testroot will consider the absence of the R³ field as if the R³ field was set to "binary-targets".
This program is a part of debhelper.
