- Updated to version 1.1.0-rc1 which enables apptainer to run without
suid and additional groups. Although this is a prerelease this is
a major advantage justifying its use.
* Added a squashfuse image driver that enables mounting SIF files without
using setuid-root. Requires the squashfuse command and unprivileged user
namespaces.
* Added a fuse2fs image driver that enables mounting EXT3 files and EXT3 SIF
overlay partitions without using setuid-root. Requires the fuse2fs command
and unprivileged user namespaces.
* Added the ability to use persistent overlay (--overlay) and
--writable-tmpfs without using setuid-root. This requires unprivileged user
namespaces and either a new enough kernel (>= 5.11) or the fuse-overlayfs
command. Persistent overlay works when the overlay path points to a regular
filesystem (known as "sandbox" mode, which is not allowed when in setuid
mode), or when it points to an EXT3 image. Does not work with a SIF
partition because that requires privileges to mount as an ext3 image.
* Extended the --fakeroot option to be useful when /etc/subuid and
/etc/subgid mappings have not been set up. If they have not been set up, a
root-mapped unprivileged user namespace (the equivalent of unshare -r)
and/or the fakeroot command from the host will be tried. Together they
emulate the mappings pretty well but they are simpler to administer. This
feature is especially useful with the --overlay and --writable-tmpfs
options and for building containers unprivileged, because they allow
installing packages that assume they're running as root. A limitation on
using it with --overlay and --writable-tmpfs however is that when only the
fakeroot command can be used (because there are no user namespaces
available, in suid mode) then the base image has to be a sandbox. This
feature works nested inside of an apptainer container, where another
apptainer command will also be in the fakeroot environment without
requesting the --fakeroot option again, or it can be used inside an
