[Qemu-devel] [PATCH v1] Makefile: remove DESTDIR from firmware file content

[Olaf Hering]

The resulting firmware files should only contain the runtime path.
Fixes commit 26ce90fde5c ("Makefile: install the edk2 firmware images
and their descriptors")

I'm fine with this patch.

Laszlo, did you use the full path for a particular reason?

Yes. The reason was that I had no idea what DESTDIR stood for. After
grepping the QEMU source tree for DESTDIR, I *still* have no idea what
it stands for.

DESTDIR seems to be an installation prefix that is not controlled through

  ./configre --prefix=...

Based on memories from other projects -- with better documentation --
though, DESTDIR looks like an install-time-only pre-prefix. In that
sense, the patch looks correct (and the vague expression "runtime path"
in the commit message starts to make some sense). Presumably DESTDIR is
used in package build scripts... Yup, the RHEL spec files use it too,
for "make install".

So, the patch is correct IMO:

Too bad QEMU is chronically under-documented (and the commit message on
the patch doesn't help much in that regard).

Thanks
Laszlo

At least the git history is public :)
