It seems to me that the exporter of those use strncpy() (i.e.
kern/init_sysctl.c) and that the structures use WMESGLEN and
KI_WMESGLEN both defined as 8.  So other than inadvertently truncated
names it at least should not cause corruption, but I think that
truncated names could also be problematic when trying to distinguish
two strings starting with the same 8 characters (is that likely now)?
Especially when the only thing that differs between two states is some
suffix like "rd" and "rw"...  After all, those are intended for
humans :)
