I think the bug with savecore(8) is that it does not descend into
subdirectories under /dev
# ktruss savecore -n | grep -e vg -e mapper
savecore: can't find device 194/1
5611 5611 savecore __lstat50("/dev/mapper", 0x7f7fff391210) = 0
5611 5611 savecore __lstat50("/dev/vg0", 0x7f7fff391210) = 0
See find_dev() in src/sbin/savecore/savecore.c
