SuSE doesn’t get enough credit for the quality of the distribution. Transactional updates, serious work towards a reproducible distribution, nano as an excellent container runtime, stability under large workloads - it’s a nice piece of engineering.
Out of curiosity, are you referring to MicroOS? I know they're written some container tools like catatonit but I haven't heard of nano.
Maybe now. 7.2 had a bug where they showed one unit when partitioning drives and used another one when writing to disk. Ask me how i find out.
