I wish you wouldn't; it seems wrong to me too.
It seems to me that allocate should create the device nodes regardless
of whether a file system was mounted, and therefore a single exit status
for success is sufficient. Even if I mounted a file system at allocation
time, I should be able to unmount it and access the device node directly
without deallocating first. Doesn't that match how it works in the
global zone?
A more basic question: This case mentions the fact that mounting file
systems during allocation is unique to TX, but I believe the difference
is simply due to historical accident. Wouldn't it make sense to provide
this feature to all Solaris users of device allocation, regardless of
whether TX is enabled or not?
