Also, we really ought to prioritize the remaining work to get us to where the sandbox root and cache or on the same filesystem in most cases. If I ask "how long does it take to make my test sandboxes?" Pants 2.16: • Mean: 15603ms • Median: 12224ms • Std: 17739ms Pants 2.17 with "same-filesystem-as-cache" sandbox root: • Mean: 83ms • Median: 25ms • Std: 162ms 🤯

By "local", you mean hardlinked, right ... ?

"local" meaning same filesystem (I'll edit)

what's your underlying filesystem? Behavior like this could vary depending on how it implements copying

Sorry to bump this old thread but my searching has left me stumped. What's the remaining work? Would the final step be changing the default

local_execution_root_dir

?

on most systems, there should not be any followup work involved. that's because (afaict from polling), most distributions stopped mounting

/tmp

on a tmpfs, and instead mount it on the root filesystem. if that's the case for you, then there is no further configuration required.
