How inode of /proc. /sys keep the same number on a given system

Hello all, I observe that between reboot inode of files in /proc and /sys filesystem keep the same number. I need to know whether I can rely on this in my program, and under what conditions this assumption became incorrect? Would inode number be the same on another system burned from the same image ? I mean when I create 10 of embedded devices, will the inode /proc of same files same between all devices? Best regards, Lev
