i think it's not normal situation, since it allows user to install more than one system logger at the same time. i'm attaching 3 patchces for syslog-ng, metalog and sysklogd with working blocking system (by added !virtual/logger in RDEPEND)
Created attachment 32025 [details, diff] metalog.patch patch for metalog ebuild
Created attachment 32026 [details, diff] sysklogd.patch patch for sysklogd
Created attachment 32027 [details, diff] syslog-ng.patch patch for syslog-ng
whats wrong with having multiple system loggers installed ? they dont clobber each other's files and the only thing they do is create a warning about having multiple system logger provides when depscan is run ...
no real issue with having multiple system loggers ...
