[HacktionLab] Wordpress file permissions and ownership: command line versus dashboard

[Marcus Valentine]

As as far as I am aware, for wordpress core upgrades, installation of 
plugins, themes etc to work through the WP dashboard, all files need to 
be owned by web-server user.

This is all well and good, but then WP admins also on occasion want to 
add their own self-written themes, plugins via sftp etc.

Has anyone figured out a permissions scheme that satisfies both 
requirements?

Thanks

Marcus
