'realpath' is not always available, fallback to 'readlink -f' if is not available. They seem to work equally well in this context.
Can you add more specifics on "realpath" is not always available," No issues with the patch itself. I would like to know the cases where "realpath" command is missing.
Not all distros have realpath. In my case, it was an internal distro we use on some test machines, so I can't really share much details about it.
Thanks.
