Hello,

The maintainer of the apptainer package has submitted updates to version 
1.1.8-1 against epel-testing:

https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2023-18a0e3fa23
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2023-44ff2475c4
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2023-b31211e2ce

I believe that the update should be considered an incompatible upgrade, 
requiring the incompatible upgrades policy to be followed, as it significantly 
changes behaviour for users who have the apptainer-setuid sub-package installed.

The update now disallows, by default, workflows that involve ext format 
container images and overlays:

```
# Before update
$ apptainer exec sif-overlay.sif /bin/date
Wed Apr 26 09:12:37 BST 2023

# Update to the testing package
$ sudo dnf update --enablerepo=epel-testing apptainer-suid

# After update
$ apptainer exec sif-overlay.sif /bin/date
FATAL:   configuration disallows users from mounting SIF extfs partition in 
setuid mode, try --userns
```

I understand that the update is related to a security issue that upstream has 
published:

CVE-2023-30549  - 
https://github.com/apptainer/apptainer/security/advisories/GHSA-j4rf-7357-f4cg

However, I don't think this exempts the update from the incompatible upgrades 
policy?

I'd also like to note that CVE-2023-30549 is dependent on and potentially a 
duplicate of CVE-2022-1184, which has been patched in EL8 and EL9, but 
admittedly not in EL7.

Thanks,

DT
