How to Enable Full-Rights File-Browsing on /?
Solution 1:
Samba maps your access to a Unix user account on the server, and the normal permissions for that user are enforced. This is therefore the same as granting a Unix user write access to these files. You either need to actually be the root
user (i.e. act as the owner of the files, which has write permission), or you need to be in a group which has group write permissions to the files. The latter is (marginally) preferable, so add yourself to the root
group and change the file permissions to allow group writes. (I'm assuming that you are aware of the security implications of doing this.)
