I don't get this sorry. Well the naming is very confusing since symlinks are already deferenced? Also I don't see a change for your stated example: $ df -L /dev/disk/by-uuid/3030-3030 Filesystem 1K-blocks Used Available Use% Mounted on udev 1454732 0 1454732 0% /dev $ df $(realpath /dev/disk/by-uuid/3030-3030) Filesystem 1K-blocks Used Available Use% Mounted on udev 1454732 0 1454732 0% /dev If I do create a symlink to a different FS, I'm not sure I get results you're expecting? $ ln -nsf /dev/shm shm $ src/df shm Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 1464412 6292 1458120 1% /dev/shm $ src/df -L shm Filesystem 1K-blocks Used Available Use% Mounted on udev 1464412 6292 1458120 1% /dev thanks, Pádraig.
