Error for getting status when using podman/toolbox

[PatrickJosh]

Hello,

I have an error using snapper on my home subvolume with some files used by podman and toolbox. There is a character special file in a subfolder of .local/share/containers with the following attributes:

c---------. 1 noeske noeske 0, 0 Feb 15 21:08 fca50e56005e85af082b358efcce51e5ef374a

It seems like snapper is not able to read this file, even with root permissions. I get the following error on trying to get the status of the subvolume:

IO Error (open failed path:/home/.snapshots/621/snapshot/noeske/.local/share/containers-old/storage/overlay/092ca4b1d42a8870e0658ba8339dbc2e56d89f4dff0ec4c5b65ddb2f3ffb9fb8/diff/usr/lib/.build-id/04/fca50e56005e85af082b358efcce51e5ef374a errno:13 (Permission denied)).

Therefore, I cannot use snapper status for this subvolume any more. As an interim solution, I created a separate subvolume for .local/share/containers but it would be nice if there is the possibility to handle that otherwise as the folder is now excluded from the backups by snapper.

I'm using Fedora Linux 35 with snapper version

snapper 0.8.16
flags btrfs,lvm,no-ext4,xattrs,rollback,btrfs-quota,selinux

If there is any additional information that I can/should provide, I'm happy to provide it.

The trailing dot in c---------. shows that the file has an SELinux security context but no other alternate access method. I assume you should fix that but I am not an expert concerning SELinux so I cannot help here.
