This is a PITA. OTOH, 'gpart show' works sanely (though you have to map from 1-origin partition numbers to partition names). If GEOM_PART_xxx is going to be kept as the default, either bsdlabel needs to learn how to interpret the partition information (preferred) or it needs to refer the user to gpart(8) and not produce confusing and erroneous error messages. Overall, gpart is definitely not a user-friendly way of managing disk space (though it is usable). As has already been noted (in part): 1) it needs to use expand_number(3) or similar to read sizes 2) the '-b offset' option to 'gpart add' needs to be made optional 3) the '-i index' option to 'delete', 'modify', 'set' and 'unset' needs to be optional (derived from the 'geom' argument if not specified - so 'gpart delete -i 3 ad4' and 'gpart delete ad4s3' are equivalent). --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --KdquIMZPjGJQvRdI Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAklVR9cACgkQ/opHv/APuIej8gCgg63iVb6GhhRLQRSAlh1r74fj EpIAmwaYr3oFIsE0zeZ+qwvqM0fYhkyt =PYFf -----END PGP SIGNATURE----- --KdquIMZPjGJQvRdI--
