I'd like to be able to migrate my hand-curated ARM-specific container config to the new

containers_x

system, before all the modules have migrated (github.com/nf-core/rnaseq/issues/1920), but right now i think I'm correct in saying that the tooling just wipes and re-creates these files. Proposing a fix: github.com/nf-core/tools/pull/4476
