I made what I thought was an innocent experimental change to the NAS shares in my /etc/fstab file on my laptop, and figured if it didn't work, the worst that could happen was I'd need to use mount -a
instead of systemd automatically mounting those shares. I was wrong. The worst that could happen was I'd no longer be able to boot my laptop.
I remember using a live session and chroot years ago to fix a problem on a broken system, but I can no longer remember the syntax I used. If someone here can remind me, I'd certainly appreciate it. All I want to do is connect the "live" session to the broken OS, so I can use use an editor to undo the change to /etc/fstab.
It's embarrassing to have to ask this, but it beats reinstalling Solus on the laptop and spending days configuring it. As I remember it, the chroot process was very simple.
