So far I used FAT32 for the SD card sharing between my Pandora and my Mac.
Now comes a point, where I'd like to use symbolic links on the SD card.
As hfsplus is supported on the Pandora OS since June 2013, I am trying to figure out the simplest possible way to share a HFS+ formatted partition between my Pandora and my Mac. I want to avoid any file permission efforts/headaches, as security does not matter in the issue, as the OpenPandora is pure leisure for me.
APPROACH 1: Change the Mac user/group to that of the OpenPandora.
As the Mac is my working machine, and the Pandora my leisure device,
this approach is excluded by principle.
APPROACH 2: Change the OpenPandora user/group to that of the Mac.
This is probably the easiest way to go.
Don't know how well the Pandora OS, libpnd and specific PNDs react to other-than-default UIDs and GIDs...
Any experiences?
APPROACH 3: Change the HFS+ mount behavior on the Pandora
3a) at best in a fashion which ignores file permissions.
On the Mac you have the option "Ignore ownership on this volume".
But technically this just causes files on the Mac to be associated with user and group id 99 "unknown".
I changed /etc/fstab on the Pandora to this:
Having considered this sources:
On the Pandora I'd need to ensure that my user gets membership in group 99 for r/w access of existing files. (Btw, how?)
But what about newly created files? They still get the UID/GID of the default Pandora user, as my test showed. Overwriting keeps UID/GID 99, creating new file/dir creates them with the default Pandora user UID/GID.
So no way around approach 2?
3b) Is there a way to mount the drive that the current user can r/w existing UID/GID 99 files/dirs AND newly created files/dirs get that UID/GID under which it is "specially mounted" (being 99)? Or no way around approach 2?
