:Actually, /@@-1:%05d is also a valid string representation of tid for
:a PFS, according to hammer_str_to_tid().  I prefer this shorter form

:Adding a support for this alternative form to hammer(8) is easy,
:but another idea is to add a support to `df' command so as it can

:Cheers.

    I'll add support for the -1 form now.  For that matter, I will also
    change hammer pfs-master to create the softlink using the -1 form.
