Is there a reason for OCI images? It is just a binary? I have all used versions in ~/.local/bin/
~/.local/bin/hugo0.145.0
~/.local/bin/hugo0.148.0
~/.local/bin/hugo0.149.0
~/.local/bin/hugo0.150.0
[...]
and a convenience symlink ~/.local/bin/hugo, pointing to my "production" version. I can easliy call whichever version I like with hugo<tab><tab>. What am I missing?
