AFAIK 'test -ef' is not POSIX.  It's mentioned in SUSv3 as 'considered
in an early proposal' but then rejected because of the non-presence in
historical sh implementations.

(This is not to say that your argument against sh on Solaris isn't
valid.  I simply haven't yet had a chance to look into the bugs it
causes elsewhere in the install.)
