H A D | geom_bsd.c | diff 108819 Mon Jan 06 18:10:41 MST 2003 phk BSD disklabels expose the controling label though the 'c' partition, and some trick is necessary to prevent further BSD geoms from attaching to that. Our old trick was to make sure we don't attach to a geom from the "BSD" class, but this doesn't work if an intermediary geom obscures this fact. Instead, calculate the MD5 checksum of the label we target and ask if anybody below us loves that label. If they do we don't. Coded by: gordon. |
