It seems to be unlikely there are systems out there relying on a boot-time mounted filesystem whose device path (or label) contains a backslash. Certainly not a great deal of those. Maybe you care to give us some concrete example. Who knows, there could be a BSD distribution, that I failed to notice, with a really bizarre naming convention for the device drivers. > Changing the syntax of /etc/fstab is a very delicate issue.

In the past 8 years there have been three different proposals and concrete implementations. You could add your own. So we would at least know what you mean with "backwards-compatible way". > > > in /etc/fstab, for whatever reason.
