The change has been reflected +in the renaming of executables/configuration 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, 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, +and since the bash-completion rule file has been renamed as well any and +all customisations here will have to be updated accordingly as well. + +[1] https://apptainer.org/news/community-announcement-20211130/ -- 2.34.1
