can we make this list complete? Does a standard centos image sufffice?

No, some things will be missing (e.g. bzip2 is not there by default, it seems).
Making the list complete here will be a PITA to maintain, I'd rather maintain it only in the code.
In practice, people should start with a base image created via a recipe generated by EasyBuild, then all should be fine.
| yum install --quiet --assumeyes patch make | ||
| yum install --quiet --assumeyes file git which | ||
| yum install --quiet --assumeyes python-pip | ||
| yum install --quiet --assumeyes gcc-c++ |

why are this all separate calls to yum? It will be quicker when combined.

That's just because they're listed separately in the code, I doubt it'll make a huge difference when we do everything in one go though?

Just timed it, total time (incl. pip install easybuild and eb bzip2-1.0.6.eb), I don't see much (if any) difference between running multiple yum install commands vs one big yum install.
In addition, the yum install epel-release has to be done separately, otherwise installing python-pip and Lmod fails.
I don't think it's worth making the generated recipe harder to read for humans for a matter of seconds at best?
