OK, I will see how I go doing that.
I was renaming the original dirs, creating replacements for /usr/local , /var/usrlocal , /var/home etc and I started getting problems with layering not finishing - I don’t have the error message that I searched for in the browser now because I reinstalled SB - I had done:
rpm-ostree install vim-X11
and rebooted but when I checked the status after it had rebooted there was a message that the previous exercise did not finish properly . . sorry I didn’t keep the error message - I should have done it on my phone or something . .
Anyway, I thought the messing around with renaming dirs and symlinking etc might have caused the problem somehow . .
After reinstalling just now and not doing any dir renaming or symlinking, the vim-X11 install worked fine . .
