But it's too hard to rewrite all drivers. HURD without sufficient amount of
drivers is life-unable in modern world. May be just source code of Linux
modules has to be simple to convert to HURD driver model?

You gain safest migration from Linux to HURD or even more:
"we say Linux and think HURD, we say HURD and think Linux". Otherwise HURD
and Linux will be animals, will eat commercial and amateur field each
other. Do you gain that?!!

Just use the same ELF format and internal structure as Linux does. Or some
like iBCS2. Binary compatibility is quite important, you see I have no time
to recompile mozilla from Linux to HURD. I'd like to cp binary netscape from
Linux to HURD, chmod, run & enjoy!

Success is total union of UNIX world against Windows NT. Most unicies MUST
BE compatible on the level NT compatible with NT. Do you want HURD to be much
more powerful than Linux? Fine idea, but Linux has to be a SUBSET of HURD!
