Current evaluation

Feature request to add a shared cache for deb/snap packages (like Charmcraft's python cache) to avoid re-downloading artifacts across pack/clean/pack cycles. Open since 2022, last activity 536 days ago, no labels, only a bot Jira-sync comment.

Suggested action: needs triage

Reason: The issue is a maintainer-filed feature request with no labels, no assignee, and no human maintainer response — only an automated Jira-sync bot comment (CRAFT-2668) from 2024-04-04. No commit or PR in the repo implements a shared deb/snap cache (searches for 'shared cache' return nothing), and the existing docs only cover an external squid proxy workaround. It has not been triaged, so it should be categorised and prioritised rather than closed.

Issue body

### What needs to get done See if we can implement a shared cache for deb/snap packages like Charmcraft has for python packages ### Why it needs to get done A pack/clean/pack cycle or packing snaps with large shared build packages can result in a lot of re-downloading of artefacts that will be checked and if necessary redownloaded anyway.
