### Discussion
Problem: Repository names are restricted to 28 characters by the groupname limit in libc6 plus our use of the iki- prefix.

Possible solution: optional use of truncated md5 (the first character needing to be a letter) hash of reponame as groupnames, restriction of usernames to 31 characters to keep namespaces isolated, check in newrepo for hash collision before actions are taken

Added 31-character limit to usernames, still need to do the rest.
