I think not. Not only
/apps. Because that alone does not exist. All files are in:
That’s why it looks like this on the hard disk:
If you mount /sqlfs from a NAS (heoretically possible) you would find this structure with the files there. You can’t do anything with that. Your NAS has no further information about the files.
If we were to save files as you know it from a NAS/Windows file server, we would not be able to do many things in EGroupware (additional fields, descriptions, links, …).
And the speed is certainly no fun then either.
It might be possible to mount EGroupware on the NAS (via GroupDAV). I don’t know what your NAS can do…
Of course, you always have to consider the permissions. That is sometimes not easy. Especially if NAS and EGroupware do not work with the same users (Auth).
Why do you want to work on / via the NAS?
What is the use case?
