Hi All, Seems that the code that is checking if an architecture has been used in a rootfile is also looking at the Core Update update.sh file. I just got this error message. Error! 'aarch64' in rootfiles files found! ./config/rootfiles/core/185/update.sh:    aarch64) Replace by xxxMACHINExxx ! The aarch64 use in update.sh makes sense as it is a command to only be run for aarch64 and not at all for x86_64. It is not a big problem and can be ignored in this case but the check code probably should only look in the common and the packages rootfile directories and sub-directories. Regards, Adolf
