All users can mount and read.
However only root can create files or folders.
We went over this already.
In an ext2 file system, the files and directories INSIDE THE FILE
SYSTEM
have standard Unix owners, groups and permissions.
If you want every file and directory to be destroyable by every single
user on the system, then you have two choices. Either you turn on the
"other" write permission bit for every single file and directory in
the file system (and make sure directories don't have the sticky bit),
or you use a non-Unix file system that does not store Unix owners,
groups and permissions at all (e.g. FAT32).
If you don't like the standard colours you get from turning everything
to 777 (read write and execute for all) then you can also use the
too-powerful "setfacl" feature to just bypass all of that in one go:
sudo setfacl -R -m other:rwx mount_directory
sudo setfacl -R -d -m other:rwx mount_directory
Although I am not sure that will get rid of the colours. But this will:
sudo setfacl -R -m group:users:rwx mount_directory
sudo setfacl -R -d -m group:users:rwx mount_directory
Now all users that are part of group "users" will have full access.
New files will automatically inherit those permissions for as long as
you want.
You could restrict that to the "disk" user group if you wanted. But
these permissions are going to be a shadowy presence to the other
permissions. And just overrule them when necessary.
