Obviously, we don't plan to package everything because some packages have high maintenance costs or they are changing too fast even for two or three...

How to package initscripts and unit files for Software Collections

Marcela Maslanova

In previous articles we mentioned tips on how to package collections, but we never wrote about initscripts, which are one reason why daemons are harder to package as a collection. I've picked a short(er) initscript to show what has to be modified if you want to run your initscript in a collection. Below is the diff between the mongodb initscript and collection version of the mongodb initscript. Currently, logfiles, pidfiles and configuration files are stored mostly as in the example...

Multiple versions on one machine can conflict with each other or create unpredictable behaviour in applications that you might not have considered dependencies. Last year, we developed Software Collections to allow you to install newer...
