On what Linux distributions can I rely on the presence of /etc/os-release?

I'm trying to find a way to determine Linux distribution name and version that would work on most (or ideally, all) modern distributions. I noticed that /etc/os-release contains the info I need on the distributions I tried (CentOS, Debian), but how safe is it to rely on the presence of it? Commands such as uname -a don't really contain the same info, and lsb_release is apparently not present on e.g. minimal CentOS. Is there a quick way to find out exactly what distros come with /etc/os-release? Moreover, is /etc/os-release guaranteed to contain NAME, VERSION and PRETTY_NAME fields?
