In OE core, we had the assumption that multiple syslog daemons could be installed at the same time. We did some work to cope with this assumption, including using update-alternatives to manage syslog related files.In meta-openembedded, rsyslog and syslog-ng have already set RCONFLICTS to avoid being installed with other syslog daemons. Checking Fedora and Ubuntu, they both disallow installation of multiple syslog daemons. (For other distros, I haven't checked.) I support forbidding installing multiple syslog daemons. Reasons are below. 1) It makes things simpler and cleaner. 2) It doesn't make much sense to install multiple syslog daemons. 3) Our current implementation has some problems. One of them is that the /etc/systemd/system/syslog.service symlink is determined by the installation order of syslog daemons, while other syslog related files including syslog configuration files are determined by update-alternatives mechanism. For more info for the /etc/systemd/system/syslog.service symlink, please refer to https://www.freedesktop.org/wiki/Software/systemd/syslog/. These two patches fix busybox and sysklogd to disallow installing multiple syslog daemons.
