This is about dropping non-PAE support, not dropping non-NX support. The NX

have PAE but not NX.
You can see this in the table here:
Dropping non-PAE just eliminates the top line in that table. NX-emu will
still be needed.

I'm also curious about this claim, as you've expressed to me in the past
that carrying it has been surprisingly trivial. In fact, since I'm the one
maintaining it these days, it's actually going to require 0 resources from

I'm curious why pushing non-PAE to universe and leaving it in the main
linux source package is a burden? Then people using non-PAE get automatic
security updates without any hassle on anyone's part. This is what the
Ubuntu Security Team manager wants:
as well as the Ubuntu Platform Team manager wants:
I'm not convinced there's enough evidence to say that dropping it from the
main linux source package will actually save any time at all.
