Generally speaking, something ends up being mounted rw and if it isn't clean, that can cause issues that may have been fixable before to become issues that are no longer fixable. This is why a lot of people put a rescue system in /boot and add it to their boot loader menu. Sadly, my /boot partition isn't large enough or I'd do that as well. If you have data you don't want to lose and no backups or only older backups, you don't want to do anything that involves risk. Booting something else and fixing file system errors is the safest way. The bad thing about this, you won't know how serious it is until you do something the wrong way. It's like me the other day. I'm susceptible to catching infections. My neighbor has the sniffles and is prone to sinus infections. I went for a visit without realizing it could be contagious. He ended up going to the Doctor and finding out he has strep. Now I'm sitting here watching for symptoms and at the ready to go to the Doctor at the first sign. Looking back, I should have waited until he was no longer sick. The other thing is, I can't turn the clock back. I've been exposed to something I can catch now. I need to remember that when he has the sniffles, treat it as a worst case scenario until I know it isn't. If you do the wrong thing with a file system, you will learn about it after it is irreparable if not careful. Treat it as bad and you are less likely to do damage. Treat it as if it isn't and you could lose data if it ends up having a problem that must be fixed first. It's about trying to limit the risk. Dale :-) :-)
