I can't answer for the unbound developers, but I have a couple of
1. For the daemon package, build it with static linking and enable the
systemd and dnstap options when building. Then package this as the
"unbound" package. Next, rebuild, with dynamic linking, and leave out
the systemd and dnstap options, and package the libraries as
"unbound-libs". The downside here is that it can be confusing.
2. Build unbound with dynamic linking. For the first build, disable
systemd and dnstap, and package the libraries as "unbound-libs". Next,
build it again, with systemd and dnstap enabled, and create two
packages: "unbound" and "unbound-libs-heavy", and make "unbound" depend
This way, other applications can just keep using the "light" library
package called "unbound-libs", but the daemon can depend on the heavy
libs package, and nothing else should need it. But the big downside here
is that there would be name conflicts. If "unbound-libs" is already
installed, and then later a user wants to install unbound, and that
wants the heavy libraries, then you can't install them into the same
place, so the library files would probaby have to be renamed.
Yuck. Having written this down, I see that option #2 is quite
complicated. Option #1 is simpler, because the daemon doesn't depend on
