I agree; lsd seems to be being overly picky, not that you personally
can do much about that.

Maybe you took Andre slightly literally; rephrasing, what are your current
fstab and nsswitch contents?  I would also ask, what do icacls and getfacl
show on your / directory (the some that is the root of the hierarchy where
things aren't working for you)?  It could be that fixing some entry there,
and recursively, will get you to a good state.
