I.e. I want the permissions to be 1000, so I can rsync to it without needing sudo.
sudo mount -o nofail,uid=1000,gid=1000,umask=007 /dev/sda1 /mnt/sda1 but that fails with
EXT4-fs (sda1): Unrecognized mount option "uid=1000" or missing value.
According to https://askubuntu.com/a/432160/676 you cannot use
uid=1000,gid=1000... why? A later thread suggest running
sudo chmod g+s -R /mnt/sda1/. Is this really the right approach to get my drive mounted as 1000 instead of "nobody"??
