Why do people keep circulating this saying? It makes no sense.
Normally, assuming only ever has the power to make an ass of the person
who did the assuming, i.e. "me", not "u and me". And even then, it's
not like you could get very far in life without making any assumptions,
so at best even that part is only sometimes true. Is the trick of
splitting a word into 3 words (one of which isn't spelled correctly
anyway) really considered clever enough to be funny when it yields
nonsense?

It's assuming without actually checking first. «This looks like junk,
so I'll just rm -rf it» rather than «this looks like junk -- uhm.
*think*. google around a bit and then removing it the right way.»

On that scenario does not seem a unreasonable action to delete it without
looking. It just 15 minutes to take it back.
I would take more time google'ing it, than reinstaling it.

But you missed my point.

Even the people here that supports the /.dev mount agrees that is not the
right place for it. It does not match the FHS, and it is a bit weird.

I understand that there only a few places to it.

I do believe that the right thing is to be disabled by default.
But this is for the policy guys to begin long flames about.

It /will/ be moved to /dev/.old-dev/dev/ at some point in the future

(I need to coordinate this with at least the makedev maintainer), but for
a different reason (#294968).

Well, I've just checked and

mount --move /dev /temp-mount-point
mount --bind /dev /where-you-want-it
mount --move /temp-mount-point /dev

works on a live system (modulo bug #282205), so you can leave it
disabled by default and provide a little helper script to turn it on on
request. Of course this is a bad idea as long as 2.4 kernels are
officially supported, so in sarge the default should be "on", and after
sarge the default can be switched to "off".

The FHS, like policy, documents current practice. If /.dev catches
on, it'll be in the FHS somehow.

Or do a boot-time check to see which kernel is running?
