I think we should provide a default, basic configuration file that we
install unconditionnally to the rootfs. The user will then be free to
provide a post-build script to tweak that file.

Please use SER2NET_INSTALL_INIT_SYSV to install that script, eg.:
    SER2NET_INSTALL_INIT_SYSV += SER2NET_INIT_SCRIPT_INSTALL

this way, the init script will only be installed if a sysv init sequence
is used (and not systemd).

Also, would it be possible to provide a systemd unit?
Ditto, use: SER2NET_INSTALL_INIT_SYSTEMD

I think we decided that uninstall targets are not needed, because
uninstall is not working completely in Buildroot. Drop it.

Always install a default configuration file, as said above.

Ditto for uninstall: drop it.

Thank you!
