fix(orchestrator): order envd.service after local-fs.target - #3043
Merged
Conversation
…tmp race updateEnvd stages the new envd binary at /tmp/envd_updated right after WaitForEnvd. #3020 set DefaultDependencies=no and dropped envd's implicit ordering, so it answers POST /init — and runs that /tmp staging — before the early-boot filesystem window settles; if tmp.mount lands mid-upload, the path lookup resolves through the fresh mount and returns ENOENT (xattr.list /tmp/envd_updated: no such file or directory). Order envd after local-fs.target so it no longer starts inside that window. The .tpl change alone is inert on warm caches: the base-layer hash keyed on (indexVersion, provisionVersion, diskSizeMB, baseSource) ignores baked file content, so a changed unit doesn't invalidate cached base layers. Fold a hash of the embedded rootfs file templates (rootfs.FilesHash) into the base-layer key so unit-file changes force a rebuild.

order envd.service after local-fs.target to stop /tmp race
updateEnvd stages the new envd binary at /tmp/envd_updated right after WaitForEnvd. #3020 set DefaultDependencies=no and dropped envd's implicit ordering, so it answers POST /init — and runs that /tmp staging — before the early-boot filesystem window settles; if tmp.mount lands mid-upload, the path lookup resolves through the fresh mount and returns ENOENT (xattr.list /tmp/envd_updated: no such file or directory). Order envd after local-fs.target so it no longer starts inside that window.
The .tpl change alone is inert on warm caches: the base-layer hash keyed on (indexVersion, provisionVersion, diskSizeMB, baseSource) ignores baked file content, so a changed unit doesn't invalidate cached base layers. Fold a hash of the embedded rootfs file templates (rootfs.FilesHash) into the base-layer key so unit-file changes force a rebuild.
