[Bug 1874953] Re: dpkg: conffile difference visualizer subprocess returned error exit status 127

[Dimitri John Ledkov]

We must not change the location of binaries from /bin to /usr/bin or
vice-versa, inside the deb.

It doesn't matter on freshly installed systems that have usr-merge, but
breaks upgraded systems.

This must be reverted.
