I rebooted ubuntu 22.04 today and it could not find the root drive and I kept being dropped to a root shell. Correlation does not prove causality, but I find it very odd that nvme0n1p5 is mounted at both / (correct) and /var/snap/firefox/common/host-hunspell (incorrect). Not sure if this is a mount/fstab thing or a snap thing or what...

$ lsblk 

│                                     

├─nvme0n1p4 259:4    0     1G  0 part 

├─nvme0n1p5 259:5    0  29.3G  0 part /var/snap/firefox/common/host-hunspell

│                                     /

├─nvme0n1p6 259:6    0   8.2G  0 part [SWAP]

I changed fstab to use the PARTUUID instead of the UUID and it finally booted, but I would like to address this issue.
