You can always have each Java runtime provide a different file, and include all of them in each Java service file using

EnvironmentFile=-/path/to/java/runtime/number/one EnvironmentFile=-/path/to/java/runtime/number/two

etc.

You can also pass a wildcard expression, avoiding hardcoding several files, maybe like this:

EnvironmentFile=-/etc/java-runtime.d/* EnvironmentFile=-/etc/java-runtime

Needs testing, but could allow the user to set a default runtime via symlink.

Alternatively, just EnvironmentFile=/etc/java-runtime and create this symlink at post_install of every java-runtime, if it doesn't exist already. To be tidy, post_remove then deletes the file if java-runtime.d doesn't exist anymore.

I can't send to mailing list as I am not a dev / TU. Isn't it possible to detect the JDK on runtime? Getting it from the java command? (or the javac command) -- Caution: breathing may be hazardous to your health. #include int main(){printf("%s","\x4c\x65\x6f\x6e\x69\x64\x61\x73");}
