The change has been reflected +in the renaming of files and environment variables, as well as a reset +of version numbers back to 1.0.0. + +Apptainer packages include compatibility symlinks to old Singularity +executables, provide bash-completion rules for both the old and the new +name, continue to honour old environment variables, and will upon +the first run import user data from Singularity directories. Therefore, +for most users it will be sufficient to deselect the old package and +install the new one, e.g.: + +emerge --deselect sys-cluster/singularity +emerge app-containers/apptainer + +However, customisations made to system-wide configuration +in /etc/singularity will have to be applied to /etc/apptainer by hand. + +[1] https://apptainer.org/news/community-announcement-20211130/ |
