FreeBSD allows you to specify this in your kernel configuration files, and
I found this very useful with external FireWire drives.

Removable hard drives can prove ``interesting'' on Linux.

Is that like General Motors ``engineering'' (e.g. where they do things like
put a bolt that holds the timing belt card behind the water pump so you
have to remove everthing at the front of the engine to pull the cylinder
head on their SOHC sixes they ran in the early Firebirds).

You mean like the IBM ``improvements'' to the Centronics printer specs on
the PC where they changed the pin-outs, and then used the DB-25 female
connectors for the printer which had been used for years for RS-232 serial
connections?  Many decried Tandy printers because they were ``non-
standard'' when, in fact, they adhered strictly to the original Centronics
specs.

The pinnacle of open systems is: when moving from vendor to vendor, the
design flaws stay the same.
