We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
Add zlib dependency to squashfs
On my CentOS system it was getting linked in (from Spack, no less)
fortuitously.
On a minimal Ubuntu system it failed until it was added as an explicit
dependency.
