NetWare was delineated into five levels of bugs to determine commercial
ship worthiness. NT is somewhat sloppier than what Novell does because
they are not running a ring 0 OS. Kernel development is Ring 0
development, so a lot of the same concepts apply:

Level I - Abends and Severe Kernel or Memory Corruption bugs, or
functionality bugs. (Oops level stuff, or Deadlock types of

Level II - Critical Bugs in peripheral subsystems, like broken
drivers that would abend (Oops), but that would not halt shipment
of core components.

Level III - boundry condition bugs, like app or subsystem problems
in low memory, intermittent LAN or obscure hardware related bugs.

Level IV - Missing Functionality, like the speaker volume not working
with pcmcia-cs-3.1.22 on an IBM thinkpad -- non-critical, but annoying.

Level V - Feature/Documentation out of sync, docs need updating, etc.

Where I came from, when you ht 0 Level I bugs, time to ship. When Linus
can post a 2.4 status that has no new Level I issues, I will put my
2.4 RPM out. To date, i just keeps dragging on, with a whole
new slew of new Level I bugs every week, but it is having fewer and
fewer of them.

He obviously posts these updates for public comment. We ship Linux,
so there's our 2 cents.
