[csw-maintainers] Information about the OS release inside the package

[Maciej (Matchek) Bliziński]

Inside a SVR4 package (that is, in things you can read from the
inode), is there any indication as to which OS release has this
package been built for?  There's practically nothing about it in
PKGINFO, except for maybe PSTAMP - if it contains the build host name,
named e.g. "unstable9s", you could infer that it's a package for
SunOS5.9.  Is there anything else that can reliably detect the OS
release?
