We should really change this > behaviour. It looks like there are actually two bugs: - install(1) does check for EOPNOTSUPP, while ZFS seems to return EINVAL. This is probably a ZFS bug. - Inside jails, (un)setting schg is not permitted and returns EPERM. We should change the VFS to return EOPNOTSUPP or install(1) to allow EPERM as well. It's a bit late, but I think it would be nice to have this fixed before 8.0. -- Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEARECAAYFAkp8fS4ACgkQ52SDGA2eCwVsKgCfRZGYFolUgC1dbOrRpxd9m/cD NOoAniSNID0qpRkcUNgufuxoSFDiy1iG =G+7y -----END PGP SIGNATURE-----help
