That's correct.  S10 /bin/sh is the legacy bourne shell, with code
originally coming from 1988, and never upgraded to the posix 1990 spec
sh(1) which is based on ksh88.

The S10 system, with the first release in 2005, is quite resilient.  And
I just tried to build and use the latest openssh 10.3p1 on s10u11 and it
worked without an issue.
