It seems to have worked because I’m no longer getting error messages when I login to the root terminal. The etc/profile looks very different now.
The real test will be when I do the next zypper dup because that’s where I was seeing all the syntax errors.
Oh and I dup’d from 42.3 Leap but it was pretty schetchy and didn’t really go as planned, the usb disc installation became a net install?
Many Thanks.
