I'm working on a embedded system. I have multiple SD cards to save copy of Linux rootfs on (kernel saved in nand). On a original SD card, where is located a system, and from this card the system is copied to another - everything works nice. Init service is working as it should.
But there is a problem on copied system on another SD cards - system is working, but it's not turning on init service, where is located for example network, sshd init, needed for a application.
Two things - when I was copying system not all of files wanted to copy (especially from /dev/, but it is normal, beacuse of aim of this files). But maybe another files weren't coppied properly?
Second thing - i'm mounting:
On tmpfs (RAM) - but i think it's not a problem (it's working good on original SD card).
Maybe I shouldn't copy rootfs, and do something else?
