In a class I’m trying to set option bootfile-name containing both a custom-set variable (model) and some text. I’m joining these with concat. But, when I use this custom variable the concat doesn’t work. If I instead use a workaround, using the option vendor-class-identifier
itself as a substring, it works. But this doesn’t practically work for me because the VCI has different prefixes depending on SW version on the client. So I need to use my own variable which I can set via a regexp match on the VCI.</div>
