# Re-grant group write across the whole cache dir. The workflow sets
# umask 002 before mkdir, but that only governs the workflow's own shell:
# BuildKit writes index.json / oci-layout / blobs from inside its
# buildkitd container under that container's umask, so the files land
# group-read-only. /var/buildx-cache carries a default ACL
# (group:github-ci-runner:rwx), but an inherited entry is still ANDed with
# the creating process's umask, which collapses the ACL mask to r-- and
# leaves every runner user except the one that wrote the file unable to
# build the next image that shares this cache dir:
#
# ERROR: failed to build: open /var/buildx-cache/<image>/oci-layout: permission denied
#
# Seven runner users share this directory and any of them can take any
# matrix row, so the last writer must not own it exclusively. chmod is
# idempotent and cheap next to the du -sb passes above; without it the
# cache is poisoned for whichever runner does not happen to build next.
