SingularityCE 4.2.2

[dtrudg]

SingularityCE 4.2.2 is a bugfix release in the 4.2 series.

Bug Fixes

• Fix regression from 4.1.5 that overwrites source image runscript, environment etc. in build from local image.
• Fall back to $TMPDIR as singularity-buildkitd root directory if ~/.singularity is on a filesystem that does not fully support overlay.
• Add more intuitive error message for rootless build --oci when required XDG_RUNTIME_DIR env var is not set.
• Avoid error in CNI network setup with newer versions of iptables that include a setuid caller check.

New Features & Functionality

• In OCI-Mode, accommodate systems configured so that they do not create a /run/user session directory. OCI-Mode will now attempt to use $TMPDIR/singularity-oci-<uid> for runtime state on systems where $XDG_RUNTIME_DIR is not set and the default user session path of /run/user/<uid> does not exist. Note that the $TMPDIR/singularity-oci-<uid> directory is shared between concurrent --oci mode invocations, and will not be removed on exit - an empty directory will remain.
