I am booting from a centos 7 live usb. I am trying to mount an NTFS filesystem, however in missing the ntfs-3g package. Attempts to use yum give an error suggesting yum is not installed - the python package for yum is present however I get the error seeing yummain module couldn't be found when running yum. I've used wget to grab the ntfs-3g package but obviously there is a dependency chain to tackle.
Is there a way to get yum working on the live usb to handle all this?
