is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?
This would mean that I need to have root privileges on every machine... which I may not have in some cases.
I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.
I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive... and so on.
Thanks!
