Groups and Permission error with image uploads ?

I have recently changed host from a shared server to a VPS box, and have had trouble with the image uploader and permissions on my server, that may have been caused by WP.

After a successful data transfer, everything appeared OK, but upon trying to to upload images in posts, i got the old faithful “is the directory writeable error”

It turns out after many conversations with my host, that the directory permissions are fine, but WP is using the wrong group identity to try and upload to the server.

Instead of using “FTPuser” as a generic group – it’s using “apache”
which the server doesn’t recognise.

my host has fixed the issue temporarily, but it will need to be maintained again in April, when the month changes and WP tries to write a new directory.

Is this issue somewthing that need to be changed in the code, and if it is can I amend it or will it need to be raised on the WP trac?

has anyone else had this issue and if so how did you solve it ?

Any further input appriciated.
