While I was planning the partitioning of a 1 TB SSD drive in an external USB enclosure (which is now a ‘portable’ backup hard drive with LEAP-15.6 on it), I had an interesting and educational (for me) and much appreciated exchange with openSUSE users.
It was proposed for me to consider (for future proofing) creating the /boot/EFI partition to be 2-4GB !! I was very surprised, as I had not been keeping up with planned future changes to openSUSE GNU/Linux.
I posted here what I learned:
This still surprises me, but then many things in GNU/Linux surprise me at present.
Despite using GNU/Linux since 1998, the past ~5 years I have allowed myself to get out of date, while GNU/Linux has been moving along. And I am now trying to play catchup.
