libnss-resolve not automatically installed



I'm currently on branch dunfell and using systemd-resolved.

I want to have glibc's NSS resolver functions using systemd-resolved.
I've noticed that the plugin was not in my image
by default.

In, nss-resolve is in PACKAGECONFIG by default.
libnss-resolve is build and packaged, but not installed by default.

To install the missing library, I've added
IMAGE_INSTALL_append = " libnss-resolve"
to my image recipe, but I wonder, if this is the right place or necessary
at all.

My assumption was that having nss-resolve in PACKAGECONFIG will
also install the related library, which is obviously not the case.

Furthermore, I had to write an append-file for base-files, such that
/etc/nsswitch.conf contains the following line
hosts: resolve [!UNAVAIL=return] files dns myhostname

Possibly, I've overlooked something essential.
I'd be very happy, if someone can shed some light on this issue.

Best regards,

Carsten Stelling
