It seems that the less interesting part is already done - geom_gettree() from libgeom, the more interesting part is some logic for directed graph (geom "mesh") navigation. Marcel, I seem to recall that there was a conversation about making fsck more geom aware (it was in context of inferring fs type from disklabel). Do you have any work in progress in this area? -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
