DH_TESTROOT(1)                    Debhelper                   DH_TESTROOT(1)

NAME top

       dh_testroot - ensure that a package is built with necessary level of
       root permissions

SYNOPSIS top

       dh_testroot [debhelper options]

DESCRIPTION top

       dh_testroot is used to determine if the target is being run with
       suffient access to root(-like) features.

       The definition of sufficient access depends on whether the builder
       (the tool invoking the debian/rules target) supports the Rules-
       Requires-Root (R³) field.  If the builder supports R³, then it will
       set the environment variable DEB_RULES_REQUIRES_ROOT and dh_testroot
       will validate that the builder followed the minimum requirements for
       the given value of DEB_RULES_REQUIRES_ROOT.

       If the builder does not support Rules-Requires-Root, then it will not
       set the DEB_RULES_REQUIRES_ROOT environment variable.  This will in
       turn make dh_testroot (and the rest of debhelper) fall back to
       assuming that (fake)root is implied.

       The following is a summary of how dh_testroot behaves based on the
       DEB_RULES_REQUIRES_ROOT environment variable (leading and trailing
       whitespace in the variable is ignored).

       -   If unset, or set to "binary-targets", then dh_testroot asserts
           that it is run as root or under fakeroot(1).

       -   If set to "no", then dh_testroot returns successfully (without
           performing any additional checks).

       -   If set to any other value than the above, then 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).

       Please note that dh_testroot does not read the Rules-Requires-Root
       field.  Which implies that dh_testroot may produce incorrect result
       if the builder lies in DEB_RULES_REQUIRES_ROOT.  On the flip side, it
       also enables things like testing for what will happen when
       DEB_RULES_REQUIRES_ROOT is set to a given value.
