As it seems now, every such utility that handles (well, at least creates) a ffs filesystem must handle SU-controlling options as command line parameters. - It seems to me that SU is just another "mode" of accessing a filesystem, just like sync and async, so it belongs with those two. If fsck needs to be aware if the filesystem was mounted with SU (why? only to cut down on repair time?), maybe the softupdates flag (as used by tunefs) could be treated as 'last mounted as' information. I am not an expert, these are just my wishes :) -- C isn't that hard: void (*(*f[])())() defines f as an array of unspecified size, of pointers to functions that return pointers to functions that return void. --------------enigE7E9E363485DFCFA2521E3ED Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFAtRnildnAQVacBcgRAh+NAJ4+WzK+8xywax69l9m3Ic0v9WPaIACfU134 DCSDIGWBA0OL/weRQj5FXM0= =r+HL -----END PGP SIGNATURE----- --------------enigE7E9E363485DFCFA2521E3ED--
