Can one reliably compile 4.0 release patches on a 4.1 release system?
Is there some patches that aren't in 4.1? If so that seem really weird
why it wouldn't be. Can you give an example?
In my network I have 4.0 and 4.1 systems. I'm upgrading the 4.0 to 4.1, but
in the mean time, if a patch is released, can I use my 4.1 build system to
build a 4.0 patch using 4.0 sources?
FYI, I change DESTDIR in order to capture only the updated binaries. Then I
make a binary patch with what was installed in $DESTDIR.
The reason for this is that I can use a single build machine running the
current release, and two source trees, current and previous.
Hopefully that explains my intentions more succinctly.
This doesn't work [1], but you can run a virtual machine in qemu,
dual-boot, or set up a second build machine.

[1] Well, it usually does, but it can break in interesting ways that are
difficult to fix.
Joachim, your footnote is what I was expecting to hear. After running a
few tests, I have been able to compile 4.0 patches on a 4.1 system, but
I'm sure I will run into edge cases that crap out sooner or later. I
guess I will mark this up as an unreliable operation.
Thanks for your suggestions. I think a dual-boot machine will be the way
I'll go.
