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 is necessary due to a e2fsprogs update
(e6114781b0fad5345a2430fac3587d618273bda2) that causes mke2fs to
enable a feature (metadata_csum) that depends on crc32c.

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.
`stripHash` documentation states that it prints out the stripped name to
the stdout, but the function stored the value in `strippedName`
instead.
Basically all usages did something like
`$(stripHash $foo | echo $strippedName)` which is just braindamaged.
Fixed the implementation and all invocations.
stripHash uses a global variable to communicate it's computation
results, but it's not necessary. You can just pipe to stdout in a
subshell. A function mostly behaves like just another command.
baseHash() also introduces a suffix-stripping capability since it's
something the users of the function tend to use.
