+ VENDOR_NAME=
+
+ The name of the OS vendor. This is the name of the organization or company which
+ produces the OS. This field is optional.
+
+ This name is intended to be exposed in "About this system" UIs or software update UIs when
+ needed to distinguish the OS vendor from the OS itself. It is intended to be human readable.
+
+ Examples: VENDOR_NAME="Fedora Project" for Fedora Linux,
+ VENDOR_NAME="Canonical" for Ubuntu.
+
+
+
+ VENDOR_URL=
+
+ The homepage of the OS vendor. This field is optional. The
+ VENDOR_NAME= field should be set if this one is, although clients must be
+ robust against either field not being set.
+
+ The value should be in RFC3986 format, and should be
+ http: or https: URLs. Only one URL shall be listed in the
+ setting.
+
+ Examples: VENDOR_URL="https://fedoraproject.org/",
+ VENDOR_URL="https://canonical.com/".
