I suppose my failed test report is CentOS6/old glibc specific (?)

@migueldiascosta http://man7.org/linux/man-pages/man2/open.2.html mentions that Linux kernel 2.6.39 is required for O_PATH

@migueldiascosta So, how do we proceed with this?

@boegel yeah, I don't see any fuse3 anywhere for RHEL/CentOS 6, so I suppose it's not possible

is there a way to require minimum versions of osdependencies? If not, shouldn't there be?

(I suppose it can be done indirectly with package names, e.g. systemd or grub2, but it's distro-dependent, less transparent and less reliable...)

@migueldiascosta We don't have support for checking versions of OS dependencies... I guess that could be useful, but it may not be that easy to implement.

We could implement support for checking the minimal kernel version though, that seems more relevant here?

We're on CentOS 7 now, as you can see from the report.

@migueldiascosta How shall we proceed with this PR? Should we look into a good way to signal that this can't be built on an older OS?

@migueldiascosta ping on this one?

@boegel it probably shouldn't hold off this PR, but in general I think having a way of specifying minimum versions of both kernel and glibc would be useful, so that eb fails with a meaningful message

@migueldiascosta Let's get this PR merged, and open an issue in the framework repo to track adding support for minimal glibc and/or kernel versions?

Going in, thanks @boegel!
