Bruce Ashfield 2119189361 treewide: bulk update patches with status field
While the insane.bbclass upstream-status check hasn't been made
default, users of meta-virtualization may have it enabled in their
distros .. so the effect is the same. We must have this tracking
tag in out patches.

This is a bulk update to add the tag and silence the QA message.

As packages get updated, the normal/routine process of checking
the patches will continue, and the status fields may (or may not)
get more useful.

Singularity is a container platform based on the principle of mobility of compute, and it is designed for use within HPC clusters. For more info see singularity.lbl.gov.

To test whether the software functions correctly, you can use singularity selftest. This is what you would expect to see:

~# singularity selftest

  • sh -c test -f /etc/singularity/singularity.conf (retval=0) OK
  • test -u /usr/libexec/singularity/bin/action-suid (retval=0) OK
  • test -u /usr/libexec/singularity/bin/create-suid (retval=0) OK
  • test -u /usr/libexec/singularity/bin/expand-suid (retval=0) OK
  • test -u /usr/libexec/singularity/bin/export-suid (retval=0) OK
  • test -u /usr/libexec/singularity/bin/import-suid (retval=0) OK
  • test -u /usr/libexec/singularity/bin/mount-suid (retval=0) OK

You can also pull a container from Docker Hub to prove full functionality (Test was performed on a Raspberry Pi 3, hence the arm32v7 part of the Docker link. Make sure you pull an image which is compatible with your hardware.) For instance:

~# singularity pull docker://arm32v7/debian:latest Initializing Singularity image subsystem Opening image file: debian-latest.img Creating 200MiB image Binding image to loop Creating file system within image Image is done: debian-latest.img Docker image path: index.docker.io/arm32v7/debian:latest Cache folder set to /home/root/.singularity/docker [1/1] |===================================| 100.0% Importing: base Singularity environment Importing: /home/root/.singularity/docker/sha256:ed4f1f0d0a0457e7f76ffb25a8d6a193007709dd312b7647cb44fc6979ec4a53.tar.gz Importing: /home/root/.singularity/metadata/sha256:89997b2c16b29c5a3a316e314172ef21b36f67cc3200b1c4d95927f716dbee83.tar.gz Done.
