N:    This package provides at least one file in /usr/lib/debug, which is
N:    intended for detached debugging symbols, but the package name does not
N:    end in "-dbg". Detached debugging symbols should be put into a separate
N:    package, Priority: extra, with a package name ending in "-dbg".

N:    debug packages) for details.

We have an override for /usr/lib/debug/xen-*.efi.map.gz but not for this.

-$ ll -h /usr/lib/debug/xen-syms-4.14-shim/
total 20M
-rw-r--r-- 1 root root 20M Sep  5 22:57 xen-shim-syms

Should we make a -dbg for this? Or include the 20M and override?
