There seem to be a lot of posts here that point to the OS as the issue. Clearly, this is not the issue as the fix lies in how unRaid assigns the subsequent share device to the bus because, I believe, the script assumes a bus address, rather than testing for free resources and assigning bus according to same. This, IMHO, results in a reassignment of resources in the OS - since it had already assigned the prior resource to enp1s0 (or whatever network int id it had previously assigned, it's forced to assign a new resource id to the new interface.) - it's a failure of the Limetech folks to properly test their scripts.
