Dev container: increase caches of to avoid recompilation? #5646
Description
What's up?
In #5644 I describe how installing mdbook and mdbook-footnote solved the problem running web:run-book.
I note that each step (installing mdbook, installing mdbook-footnote, web:run-book) downloads and/or compiles a whole slew of files, many of them the same. For example:
- all three compile "unicode-ident v1.0.22"
- all three compile "proc-macro2 v1.0.103"
- the first two steps compile "itoa v1.0.15", the last compiles "itoa v1.0.16"
Is there a way to avoid re-compilation? Thanks
