I have a Live red hat 7 USB that I made, and I dd'ed the first 5 gigs of it into a .raw.gz that I then zcatted to the new USB. The new USB boots, however for some reason it is booting into emergency mode. The only errors I found in journalctl -xe were " Failure to mount sysroot". Is there any way I can work around this? Will it make a difference if I dd the source USB while it is not running? any advice would be helpful and thanks in advance! Please note that this same process worked with an openSUSE rendition of the entire project.
update: I formatted the source USB, and then zcatted the exact same image back onto it, and to my surprise it boots up as if it was never reformatted maybe the "new" usb is corrupted?
