DH_TESTROOT(1) Debhelper DH_TESTROOT(1)
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 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.
