admin/run is a wrapper to run and log commands in production containers. It is currently used for cron jobs but can also be used to run one-off commands in the same containers (production-cron, json-dump, search-indexes-dump, sitemaps).

It doesn’t necessarily work outside of this environment because it makes a number of assumptions at first glance:

1. User has to be "musicbrainz"
2. Environment variable "PATH" is arbitrarily set
3. Environment variable "PERL_CARTON_PATH" is arbitrarily set
4. Logs are written under subdirectories of "~/log/"
5. Those subdirectories have to be created beforehand

It should be more versatile so as to be easier to use in a development setup and for mirrors as well, from installation steps to maintenance routines.
