Also as an addendum, last time I checked, if your entry for root in

for you to recover the situation from.
That's no longer true as I understand it (and was why i asked you for
a technical reason).
See
Check the source and you will find it *is* still the case.
However that isn't a reason not to change the shell of the root user but
the addendum statement Sean made is true.
For OpenSolaris distributions that use the ON $SRC/cmd/sulogin as their
sulogin (and I believe currently that is all distros) see:
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/sulogin/sulogin.c#246
and for what shell is set to see line 96 of the same file.
If the entry for root in /etc/passwd or /etc/shadow isn't mangled then
we use the same single() function but pass on responsibility for execing
the shell to /sbin/su.
