hello hackers, I recently ran into a issue with a storage server that has some of the drives in gpt vs mbr, tracked it down to a 64 char limit that is preventing aliases in function make_dev_physpath_alias. I was curious if there was any reason why this couldn't be bumped from 64 to 128 which would make room for the device paths of gpt roughly around 94 and 96 chars long. - #define SPECNAMELEN <http://fxr.watson.org/fxr/ident?im=3;i=SPECNAMELEN>; 63 */* max length of devicename */ + *#define SPECNAMELEN <http://fxr.watson.org/fxr/ident?im=3;i=SPECNAMELEN>; 127 */* max length of devicename */* http://fxr.watson.org/fxr/source/sys/param.h#L106 Jul 14 22:10:17 fbsd9 kernel: make_dev_physpath_alias: WARNING - Unable to alias gptid/4d177c56-ce17-26e3-843e-9c8a9faf1e0f to enc@n5003048000ba7d7d /type@0/slot@b/elmdesc@Slot_11/gptid/4d177c56-ce17-26e3-843e-9c8a9faf1e0f - path too long Jul 14 22:10:17 fbsd9 kernel: make_dev_physpath_alias: WARNING - Unable to alias gptid/4b1caf38-d967-24ee-c3a0-badff404e7ed to enc@n5003048000ba7d7d /type@0/slot@5/elmdesc@Slot_05/gptid/4b1caf38-d967-24ee-c3a0-badff404e7ed - path too long -Selphie (Estella Mystagic)
