[ sorry for the wrong bugreport in the last version of this entry ]

It seems as if I can only add my own file to the annex, even if I have group write permissions. Is that correct? Can that be circumvented other than copying/deleting the large file?

Here is some demonstration:

> git init
> git config user.name dtr
> git config user.email dtrn@dtrn.com

> dd if/dev/zero of=test2.bin count=1000

> ll
-rw-rw-r-- 1 dtr dtr 512000 Sep 16  2013 test2.bin

> sudo chown someone test2.bin
> ll
-rw-rw-r-- 1 someone dtr 512000 Sep 16  2013 test2.bin

> git annex init
> git annex add test2.bin
add test2.bin (checksum...)
