# Pinned: every BuildKit >= v0.31.0 bundles a runc whose maskDir() mounts masked paths
# with "nr_blocks=1,nr_inodes=1", which the Docker Hub build host's Ubuntu 20.04 5.4
# kernel rejects with EINVAL, failing every RUN step in container init (runc#5348).
# v0.31.x ships runc 1.3.6 and v0.32.x ships runc 1.4.3, both affected; v0.30.0 ships
# runc 1.3.5, the last release before maskDir(). Drop the pin once BuildKit ships
# runc >= 1.4.4 (note runc 1.5.0 predates the backport and is also affected).
