You're right.

It is adding the "fix" that would force the prompt that the maintainers config is different than the local one since the fix is what would change the config file.

Even that isn't necessarily true. If they add a new file to /etc/sysctl.d/ then they're not changing the original file at all. This would also have the advantage that upon package removal they can easily purge that file, again without impacting the original.

Good point - I was thinking of /etc/sysctl.conf

Never really look at that (currently) empty folder and forgot it was there.

For the dosemu situation from #505247 - dosemu low memory sysctl - Debian Bug report logs
Subject: dosemu low memory sysctl
Date: Sat, 24 Oct 2009 20:17:44 +0200

Hi

dosemu has been patched to to address the vm.mmap_min_addr = 0 issue
(implemented before the actual svn revision 1988). I know of no
application, that does not run. For this patch to work, the vm86 mode of
the processor has to be simulated, which is an performance issue. To use
simulated mode for vm86, you have to set $_cpu_emu = vm86 in
dosemu.conf. You get a warning for using an experimental feature.

Reinhard


Based on comments inside dosemu.conf vm86 is actually the default if you're running a 64 bit system.
# Usage of cpu emulation: "off" (default on x86),
# "vm86" only (default on x86-64) or "full" (vm86 and DPMI, experimental!).
# Use "vm86sim" or "fullsim" to use simulation instead of JIT code generation.

# $_cpu_emu = "off"

There are loads of win16 apps out there and many of them work just fine under wine.

I was looking for that info and found this thread. So where is this BSD kernel? No sign of it in a recent net squeeze install - has the plan been abandoned?

Thanks for the quick reply! Doesn't look like Debian are confident of this hybrid as yet...

Yes I'm already running a BSD but looking forward to the wider choice of packages and less filespace demanded by Debian.
