Is 'compare' broken in rolling?


I tested like this (on VyOS 1.2.0-rolling+201811080337):
Only changed one interface description, ‘commit’ ‘save’, ‘compare 0’ and maybe the complete configuration is marked as new.
‘compare’ with other revisions the same result.

vyos@r1# set interfaces loopback lo description “test”
vyos@r1# commit
vyos@r1# compare save
[edit interfaces loopback lo]
>description test
vyos@r1# compare 0
