I saw it happen with sshfs over FUSE. 8-/ Yet another reason to put in a check before performing the chmod. > Further, I've found some inconsistent behavior with ext4: chmod on the > magic symlink fails with EOPNOTSUPP as in Florian's test, but fchmod > on the O_PATH fd succeeds and changes the symlink mode.
