There was a problem hiding this comment.
I think this is a sensible workaround! Where possible, we should try to actually set the right user id and home directory (sbx_user1051), however in cases where we cannot influence the user, it makes sense to have this fallback.

Context
When a container starts with
--user=1000:1000,AddUseris never called so there is no/etc/passwdentry. Combined withUnsetLsEnvsstrippingHOME, Node'sos.homedir()and AWS SDK config loading throwENOENT.Changes
EnsureHome()runs once at startup afterUnsetLsEnvs. Ifuser.Current()fails (no passwd entry), it setsHOME=/tmp. The normal root-start flow is unaffected.Testing
Seetest-homedir.md(will be removed) for a manual end-to-end test using a Node.js 22 function that callsos.homedir()with--user=1000:1000.Towards DRG-715
