Hello Adolf, Oh, my favourite hobby, loop devices in containers. They are such fun.
I would most likely expect the kernel to have added any restrictions, but in a release cycle, this would be a very surprising. Could you do the following for me: * Enter the shell with ./make.sh shell * Create a temporary file: dd if=/dev/zero of=/tmp/test.img bs=1k count=2880 * Put a FAT32 filesystem on it: mkdosfs -F 12 -n "IPFIRE_EFI” test.img * Mount the image: mount -o loop test.img /mnt, this should fail * And so that we have some debugging information, could you run the mount comment with strace in front of it, so that we see which syscall it is that is failing. -Michael > On 3 Mar 2026, at 11:04, Adolf Belka <[email protected]> wrote: > > Hi All, > > I mentioned this issue in yesterday's conf call.
