first of all ignore /etc/release. (you should know that :) )
only kernel is what counts.

jh at login [login]:/home/jh > ssh unstable10s uname -a
SunOS unstable10s 5.10 Generic_150400-17 sun4v sparc
SUNW,SPARC-Enterprise-T5220
jh at login [login]:/home/jh > ssh unstable10x uname -a
SunOS unstable10x 5.10 Generic_147441-19 i86pc i386 i86pc


second:

h at login [login]:/home/jh > ssh unstable10s "pvs -s /usr/lib/libc.so |head"
        libc.so.1:
                _PROCEDURE_LINKAGE_TABLE_;
                _GLOBAL_OFFSET_TABLE_;
                _DYNAMIC;
                _end;
                _etext;
                _edata;
        SUNW_1.23:
                mkdtemp;
        SUNW_1.22.7:
jh at login [login]:/home/jh > ssh unstable10x "pvs -s /usr/lib/libc.so |head"
        libc.so.1:
                _edata;
                _PROCEDURE_LINKAGE_TABLE_;
                _etext;
                _GLOBAL_OFFSET_TABLE_;
                _end;
                _DYNAMIC;
        SUNW_1.23:
        SUNW_1.22.7:
                asprintf;


they backported mkdtemp to Solaris 10 Update 11. I think maybe even
somtime via a patch.
And also put in in 1.23 which I still think will mess things up
sometime. Anyway avoid mkdtemp.
Our default map files should to that.
