When you have a similar problem on Linux, and you home is inaccessible or read-only, you get an almost screen-sized dialog, no desktop background (something hard to replicate on your settings), and the system theme (that is probably different from your DE's default).
of course it's always been the unix way to be strong-silent without have a lot of "informative" message clutter, so I'm generally sad to see it friendlied up.
Unix is for silent success. I don't think there is any overall culture about what to do on errors.
But anyway, when you lose your home dir, your computer becomes obviously broken. Your a bit more than mine, but it's the obviousness that is important. (Anyway, I don't gain anything from the extra functionality my system holds when compared to yours. It's always a hardware problem, a X session is useless.)

Windows 7 left extended support two and a half years ago, mainstream support seven years ago, and hasn't been in development for eleven years. (Like commenting from Windows XP in 2001 that Windows 3.11 in 1993 had an unhelpful dialog box).
WTF. That looks really amateurish. Why couldn't they make the notification window larger?
