It is not an halevt-mount message, but a message from HAL, that 
halevt-mount merely relays. So I doubt anything can be done at the
halevt/halevt-mount level.

Same here. It is an error message generated by HAL.

For these, I think that the issue is in HAL (or, possibly, in the hal
or polkit configuration), so I don't think anything can be done in halevt.

HAL specific variables should not be documented in the halevt 
documentation itself in any case. If you have an url for all the
hal variables, I'd be happy to make a link in the manual.

Indeed. It would be worth mentionning in the documentation, I'll add
a section.

I used ivman as inspiration for the design of halevt, but it is definitely
different. For example, it tries to avoid the design issues of ivman (most 
of them having been reported to me by Rohan). So I am not very worried 
with differences with ivman syntax, any similarity being more or less 
luck. The important thing is that it is properly documented.
