@Tom-Elliott This would be just one use case. Yes we want to use the osID for several other things too. For example we have some really exotic SLES installations that we want to treat seperately to normal linux distributions. So we just dont want to go the hacky way, mounting the os partitions and searching for special files so we can identify its a sles installation…
For the Windows 11 thingie:
We have very custom postdownload scripts that rely on the hardwarename/osID/ARCH/ stuff so adding own osID’s would make it much easier for us to differ between the Operating systems and unattended files.
