Installing the kernel-modules RPM resolves the issue. Should this package be installed by default? |

This issue was discovered when trying to run SingularityCE on Alma Linux 9. On closer inspection it appears appears that the squashfs module is not present in a default virt-install of Alma Linux 9 from the minimal ISO because the kernel-modules package is not present. Installing kernel-modules fixes the issue, and this may be the intended behavior. I'm a little confused, mainly because a RHEL9 install had the full kernel packages including modules present - but this was from a 'DVD' ISO... as there is no 'minimal' ISO on the RHEL download page.
