Hi,

yesno!

Some things can't be repaired by systemd-nspawn. One exception for
example is GRUB2. Repairing GRUB2 not necessarily requires a chroot, but
depending on what you want to do, you can't replace a chroot by
systemd-nspawn for this purpose.

You can even boot another Linux by systemd-nspawn. Note: Below I also
boot Ubuntu by my Arch Linux install.
The mentioned kernel 4.19.246-rt110-0.1000 is not the Ubuntu kernel,
it's the kernel of my Arch Linux install.
