I would like to know how you deal with the issue of owner / permissions for wordpress multisite.
Regarding this documentation: http://codex.wordpress.org/Hardening_WordPress#File_Permissions
Some neat features of WordPress come from allowing various files to be writable by the web server. However, allowing write access to your files is potentially dangerous...
It is best to lock down your file permissions as much as possible and to loosen those restrictions on the occasions that you need to allow write access...
What permission scheme do you use normally? Do you change file permissions each time you need to update or install something from wordpress? Or do you update from sftp and you never do anything from wordpress?
Thanks a lot!
