commit b57deee8178190a7ecc75290fa13cf7daabc2c66
Author: A. Wilcox <AWilcox at Wilcox-Tech.com>
Date: Sun May 15 05:04:10 2022 +0000
Make netgroup support optional
On at least Linux/musl and Linux/uclibc, netgroup support is not
available. PolKit fails to compile on these systems for that reason.
This change makes netgroup support conditional on the presence of the
setnetgrent(3) function which is required for the support to work. If
that function is not available on the system, an error will be returned
to the administrator if unix-netgroup: is specified in configuration.
(sam: rebased for Meson and Duktape.)
