The variable does more than just influence server.el.  It makes
file-attributes more accurate, which has its own benefits, most
prominently in Dired.

No, I tried to help you work around the problem (and get a better
filesystem while at that).

I couldn't know that, could I?

I do, and it does -- mostly.

The code in server.el assumes a Posix filesystem.  We are trying to
get it to work nicely on Windows, when some of these assumptions don't
hold.  IOW, no one specifically assumed users do not have FAT32.

It is a more or less common knowledge in the Posix world.  But I do
agree that the message text should be more self-explanatory.

If the message is explicit enough, it will explain itself.
