i've tried to add similar functionality to the unbound debian package by
adding this line to our default config:
include: "/etc/unbound/conf.d/*.conf"
and shipping an empty /etc/unbound/conf.d directory in the package for
users to place local config. unfortunately, without any filename
matches, glob() returns GLOB_NOMATCH and this causes config file parsing
to fail:
/etc/unbound/unbound.conf:17: error: cannot open include file
'/etc/unbound/conf.d/*.conf': No such file or directory
read /etc/unbound/unbound.conf failed: 1 errors in configuration file
this goes away if i put at least one file that matches the glob into
that directory, but i don't want to have to ship a dummy empty
"do-not-remove.conf" file in the conf.d directory in order to get the
config to parse correctly (what if the user removes it?). could this
feature be updated so that a lack of glob matches is treated as
"success, but no files included" rather than failure to parse the
config? (possibly made contingent on the existence of the directory of
the dirname() of the wildcarded include: parameter.)
What I did was put commented out examples (example.com.conf,
example.comf.key) in those directories. Without those, the users will
have a hard time figuring out the syntax anyway.
eg I have example.com.conf:
# Example of an override of the "public DNS tree" with an "internal view"
# override, for example to add an internal-only corporate DNS zone.
#
# The stub-zone/stub-addr must point to AUTHORITATIVE servers. If you want to
# point to an internal RECURSIVE server, use forward-zone/forward-addr instead.
#stub-zone:
# name: example.com
# stub-prime: no
# # if you could trust a lookup, use:
# stub-host: a.iana-servers.net.
# stub-host: b.iana-servers.net.
# # else specify the IP's using:
# stub-addr: 199.43.132.53
# stub-addr: 2001:500:8c::53
# stub-addr: 199.43.133.53
# stub-addr: 2001:500:8d::53
