xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.
9p doesn't provide any suitable cache modes, so fix this by disabling
caching.
Also, remove a now unnecessary sync in the test driver.
When updating to cpio-2.13 in fe758f5fa3,
a patch from SUSE was dropped. This patch was intended to resolve
CVE-2015-1197, and introduced the '--extract-over-symlink' option to
disable its own effects.
The CVE-2015-1197 was fixed in cpio-2.13 release[1] by other means,
making this patch useless.
Given that this patch is no longer used, we do not need to disable its
effects anymore with the `--extract-over-symlink` argument switch.

Whenever we create scripts that are installed to $out, we must use runtimeShell
in order to get the shell that can be executed on the machine we create the
package for. This is relevant for cross-compiling. The only use case for
stdenv.shell are scripts that are executed as part of the build system.
Usages in checkPhase are borderline however to decrease the likelyhood
of people copying the wrong examples, I decided to use runtimeShell as well.
There is a function params `kernel' intended to specify which kernel to use.
It defaults to `pkgs.linux`.
But when we override `kernel', compiling and using two kernels seems not to be the intendend bevavior.
This reverts commit f777d2b719.

This breaks evaluation of the tested job:
attribute 'diskInterface' missing, at /nix/store/5k9kk52bv6zsvsyyvpxhm8xmwyn2yjvx-source/pkgs/build-support/vm/default.nix:316:24
Previously the Release.xz URL would show up with a new hash whenever
debian releases an update. By using archive.org we should have a stable
source for those. I wasn't able to find the equivalent in the debian
world. Maybe they don't keep all the different Release files around..
With the recent update of BusyBox to version 1.29.0 in
d6aa506e3b there is now a new dependency
on libresolv.
This now throws a runtime error when executing ash, eg. whenever we do
something like this:
nix-build -E 'with import ./. {}; vmTools.runInLinuxVM hello'
The resulting error will be:
.../ash: error while loading shared libraries: libresolv.so.2: cannot
open shared object file: No such file or directory
I tried to override BusyBox with enableStatic, but that still requires
parts of glibc:
Static linking against glibc, can't use --gc-sections
Trying libraries: crypt m resolv
Library crypt is not needed, excluding it
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Final link with: m resolv
In the long term maybe switching to a more minimal C library such as
musl would make more sense, but for now I just added libresolv.so to the
initrd which fixes the runtime error.

This commit adds the CentOS 7.4 base image from the CentOS mirror, for use with
building RPMs or evaluating Nix expressions in a CentOS image.
When CentOS 7.5 comes out, I will swap this URL to the permanently vaulted image.
