@knc1:
Good catch on the functions thing, c/p oversight that I distinctly remember fixing, but that must have been on another KUAL extension ;p.
Good to know how mount is *supposed* to behave, I'll take a look at it, but since the defensive approach is in there now, it'll probably stay, can't hurt to be too careful [well, unless you botch the checks like I initially did ^^]

BB mostly seems to honor what the mount() syscall returns...
