Comment 6 for bug 1892029

Thank you for the detective work and the correction on the root cause, @hmlanigan.

Would it be better just to factor out the dependency on at altogether? Installing via yum will fix the issue on CentOS, but won't fix the issue on other non Ubuntu Server machines, where at isn't necessarily installed by default. (It's not installed by default on Ubuntu Desktop, for example -- it's not necessarily a package that we can rely on appearing on any given system.)

Do we use the system package manager to install other dependencies? If so, we might need to plan some work to find alternatives for those packages, lest we find ourselves with an ever expanding list of conditional package manager calls to make, depending on the detected Linux distro. Eek!
