Systemd introduced a metadata field in /etc/os-release for a vendor to indicate the end of support https://www.freedesktop.org/software/systemd/man/os-release.html#SUPPORT_END=
It would be helpful if facter added this value if present to the OS information
Hi Pat Riehecky,
This sounds like an interesting feature! We don't currently have bandwidth to look at this, but if you wanted to open a facter PR we can take a look!
