During the upgrade if we want to pause it (e.g. to get some work done), what is the best way to do that? I'm running on Ubuntu 12.04.
E.g. I ran "bitcoind -daemon" (I wish I could leave that daemon running and have bitcoin-qt reference it....)
Is it safe to do a "bitcoind stop" in the middle of the upgrade? Will I lose any work already done?
Or should I stop the process in mid-stride (kill -stop ) and kill -cont it later?
