How do I determine current partition
I have several linux root partitions - copied from my default root partition. My default root now refuses to boot (due to a stupid error of mine). However, another root partition will boot, but I have not been able to determine which. blkid and others list partitions by device letters and UUID, but I need to be sure which partition I am working on/from. Funny thing is fstab is referencing my default root partition, but the one being booted is a copy. Is there a (CLI) way to find the UUID (preferable) or the /dev/sd? currently active?
