@ -34,7 +34,13 @@ For the `groups` attribute, it is possible to add a group by doing
`groups,=<newgroup>` and to remove by doing `groups^=<oldgroup>`

See nodegroupattrib(8) command on how to manage attributes on a group level. Running
nodeattrib on a group will simply set node-specific attributes on each individual
member of the group.
Additionally, if wanting to change from a node level attribute value to inherit from a
member group, it is required to use '-c' to clear the attribute. Conversely, assigning
to a blank value will allow masking a group defined attribute with an empty value.
