I believe such a mechanism already exists, although it might be somewhat misnamed: the vfs.root_mount_hold sysctl. Some rc scripts use the root_hold_wait() function, which uses the sysctl. Perhaps the ZFS scripts should do the same? Note that this is somewhat more involved than just CAM - you also need to wait for GEOM to settle. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
