Make your uname and place it to current one.

One thing is that u could set an alias to the uname command, or else create your executable to call your desired uname and put it in any of your directories found in your path,after renaming the actual executable to something like uname_act.

On Solaris you can use dtrace to temporarily change the OS version outputted
by uname(1)

(From Solaris Developer Network submission by user Rajadurai)

#!/usr/sbin/dtrace -qs
 
#pragma D option destructive
 
BEGIN
{
       printf("Changing output of uname for pid %d and its descendants...\n",$1);
}
 
syscall::uname:entry
/progenyof($1)/
{
       self->addr = arg0;
}
 
syscall::uname:return
/progenyof($1)/
{
       copyoutstr("5.9", self->addr+(257*2), 257);
}
