Public bug reported:
Running 'stat' from coreutils-from-uutils in a chroot fails:
$ lsb_release -d
Description: Ubuntu 25.10
$ stat /
stat: cannot read table of mounted file systems: No such file or directory
Works fine on Plucky with 'stat' from legacy coreutils:
# lsb_release -d
Description: Ubuntu 25.04

$ sudo debootrap questing questing
$ sudo chroot questing stat /

One of the side-effects of this is that grub-pc installation in a chroot fails:
