[Buildroot] [PATCH v2 1/2] xlib_libpciaccess: Rename package to libpciaccess

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Dear Bernd Kuhls,

Not sure why you're replying to me with a weird gmane address. I'm
replying with the Buildroot list Cc'ed instead.

I certainly now that ARM and PCI do not exclude each other, as I've
myself written the PCIe support for one ARM platform, and I'm the
maintainer of it in the Linux kernel:

  http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/MAINTAINERS#n7003

But while *some* ARM platforms do have PCI, a number of them don't have
access to it.

Ok, fair enough, makes sense.

Basically: never, because choices are not randomized.

However, with the "preseed" stuff that Yann and Arnout have posted, we
might be able to preseed the random package select with certain
options, and therefore the autobuild-run script could be improved to
sometimes select the modular variant of the X.org server. I've added
Yann and Arnout in Cc so that they can comment on this.

Thanks!
