Pants

Hi! Is it a good idea to use an NFS volume to share the pants cache across CI runs ?

I guess not. It didn’t not work.
```Got hash collision reading from store - digest Digest { hash: Fingerprint&lt;83110679b09ce09d8h565f141eaa6dd95b25b74e27ae1b150eee3dfba766f4b4&gt;, size_bytes: 3845079 } was requested, but retrieved bytes with that fingerprint had length 8. Congratulations, you may have broken sha256! Underlying bytes: [77, 255, 89, 97, 0, 0, 0, 0]```

yikes. yea, I expect that LMDB’s locking does not work on NFS.

Apologies for “grave-digging” very old threads but just wanted to chime in that we’re also <https://pantsbuild.slack.com/archives/C046T6T9U/p1717033822896169?thread_ts=1711026052.698879&amp;cid=C046T6T9U|experiencing weirdness> when pointing pants’ local cache to a network mount.

We couldn’t get `PANTS_NAMED_CACHES_DIR` cached on EFS. (`PANTS_LOCAL_STORE_DIR`  had a different set of issues so we gave up that thinking that that dir is not meant to be shared)
