Ubuntu accessing MacOSX user folder.

[Dave Woyciesjes]

I've got my MacBook Pro dual booting OSX 10.6 and Ubuntu 11.10. Now
what I want to do is to be able to use the Documents (and others) folder
in the OSX user folder (/User/Dave/Documents) with Ubuntu as well.
Yes, there are many how-tos that mention using a third partition for
this. Since I don't have a lot of extra space (and I'd rather not
anyway); I need to figure out a good way to get the permissions right...
Since OSX user number is 501, and Ubuntu start at 1001; that's a bit of
a hiccup.

One thought I had was to create a group on each os, "crossover" and set
the groups to have matching numbers as well. Then in Mac OSX I would
give the crossover group rwx permissions on the folder I want access to.
I'd also have to add a line to fstab to get the OSX partition mounted
automatically as well.

This all make sense, or am I headed down the wrong (or bad?) path?

This sounds like a reasonable approach.

Created the crossover group in OSX, and added me as a member. Now to
determine what the group number is. And no, OSX doesn't keep it in
/etc/group. Already looked in that...

I do not know if Mac OS X provides id, but try it in the terminal:

id user_name

Thanks much. Added to notes....

In my goofing around, I discover that the MacOSX group "staff", which
is the default group that the user's files are a part of; the number for
that maps to the "dialout" group in Ubuntu. So I don't need to create a
matching groups in each OS.
I can use the standard MacOSX methods of giving the "staff" group the
desired permissions.
Added a line to fstab to automount the mac partition, and added the
force option to get RW.

I've seen a few old posts about getting Mac to read ext4, but none of
them give me the warm fuzzies enough to try them. Anyone have any
experience with a particular method?
