Solaris did depend on a 100% compatible Bourne Shell, but Sun changed this on
April 2010 with OpenSolaris.
Between april and August 2010, aprox. 3 scripts have been made non-portable and
depending on ksh.

Unless you install the "osh" compile variant of the Schily Bourne Shell on
Linux, there is no Bourne Shell compatible shell on Linux.

ksh is not 100% Bourne compatible, it is just that Scripts written for the
Borne Shell have been written more carefully to not expose the problems.
If you like to get a list of incompatibilities, you may look at the Schily
Bourne Shell web page that lists all changes required for POSIX compatibility
in read:
http://schilytools.sourceforge.net/bosh.html
The man page linked there contains a section COMPATIBILITY that lists
incompatibilities between the Bourne Shell and the POSIX shell.
