   Hi @worldspawn , thanks for writing in.
   
   I'm a bit confused. You've shown in your config that you're setting up a standalone node. But you seem to be trying to set parameters (such as `-name` and `-cookie`) that only make sense for a clustered node. The debian setup is intended to select the expected configuration for standalone nodes, which is `-name couchdb@127.0.0.1` and the default (and basically unused) `-cookie monster`.
   
   The only parameter that is used when doing a standalone node configuration [is the `bind_address`](https://github.com/apache/couchdb-pkg/blob/master/debian/couchdb.postinst#L143-L161).
   
   Also, you _have_ to set the password to use the `debconf` setup for either standalone or clustered mode, otherwise the postinst script will fail, leaving you in a half-configured state. There's no need to go through the CouchDB setup wizard using the Debian preconfiguration functionality for a _standalone_ node; the autoconf script automatically completes this for you by creating the _`users` and `_replicator` databases. So go ahead and set your admin username and password.
   
   I can see the desire to change the cookie for a standalone node, perhaps to prevent `remsh` by a local user on the box from accessing the Erlang runtime, so if this is your intent I can enhance the setup script. But I think for most users in standalone mode, deviating from naming the node from `couchdb@127.0.0.1` is a significant mistake. The one exception is if you are running multiple CouchDB nodes on the same machine (and, not inside of Docker containers/chroots/jails/similar), and this isn't really possible using the packages anyway.
   
   Finally, setting anything other than `couchdb@FULL-IP-ADDRESS` or `couchdb@FULLY.QUALIFIED.DOMAIN.NAME` is no longer a recommended configuration setting, see the comments in [vm.args](https://github.com/apache/couchdb/blob/master/rel/overlay/etc/vm.args#L13-L28).
   
   Happy to help more if none of the above is clear or useful.
