features which should be good to go:
* user groups
* assigning permissions by group
* dynamically created volumes based on username/groupname
* rebuild vfs when new users/groups appear
but several important features still pending;
* detect dangerous configurations
* dynamic vol below readable path
* remember volumes created during previous runs
* helps prevent unintended access
* correct filesystem-scan on startup
* allow mounting `/` (the entire filesystem) as a volume
* not that you should (really, you shouldn't)
* improve `-v` helptext
* change IdP group symbol to @ because % is used for file inclusion
* not technically necessary but is less confusing in docs
primarily to support uploading from Igloo IRC but also generally useful
(not actually tested with Igloo IRC yet because it's a paid feature
so just gonna wait for spiky to wake up and tell me it didn't work)
connections from outside the specified list of IP prefixes are rejected
(docker-friendly alternative to -i 127.0.0.1)
also mkdir any missing folders when logging to file
* mention cloudflare-specific nginx config
versus.md:
* seafile has a size limit on zip downloads
* seafile and nextcloud are slow at uploading many small files
u2c: improve error message in funky environments
