Remount /home rw when it's errored to ro

[Ralf Mardorf]

It wasn't smart (SMART ;) to open a new thread for this. Karl is right,
but not dramatic enough. The remounting might happen by UUID or lable.
It's interesting to now if the drive letter does increase.

Sometimes external drives connected by USB suffer from IO errors on my
machine. Without remounting I can see that sdh becomes sdi etc. ... in
short, most likely something is fishy with my computer. It required
time wasting troubleshooting. Usually it's the drive that is broken.
Either way, you need to troubleshoot by using another/new drive. If you
have good luck the drive is borked.
