If it's helpful, we can use the ppa:couchdb/dev for this, and use couchdb2 as the package name for the interim. Dropping a 2.0 over top of a 1.x install would be very much against Principle of Least Astonishment. This approach is very common in FreeBSD ports, for example with puppet3 and puppet4 to give people a clear distinction. > > - How does CouchDB handle signals?

There are a number of daemons to help address this, but IIRC all of them have non-ALv2 taints and/or heavy dependencies. https://github.com/ShoreTel-Inc/erld https://github.com/jkingsbery/sighandler https://github.com/erlware/erlnixify A competent C programmer could make short work of a GPL-free version of erld (hint hint) though. Things a signal handler needs to address: - rotating logs SIGHUP? - SIGTERM & friends for shutting down - terminating BEAM if/when it becomes unresponsive a la heart - ... others? The new systemd approach (& presumably docker too) means that the whole of couchdb runs in a namespace which is then cleaned up. I really like this, considering how much effort was consumed in getting the original couchdb script to work correctly. A+ Dave
