Description Tibor Vass 2019-06-11 23:36:32 UTC 
Repro:
$ cd /tmp
$ ln -s target_does_not_exist symlink

Coreutils (expected):
$ readlink -f symlink
/tmp/target_does_not_exist
$ realpath symlink
/tmp/target_does_not_exist

Busybox (incorrect):
$ readlink -f symlink
realpath: symlink: No such file or directory
$ realpath symlink
realpath: symlink: No such file or directory
