John, All,
On 2018-05-01 13:28 +0100, John Keeping spake thusly:
> When rebuilding a package, simply appending the package's file list to
> the global list means that the package list grows for every rebuild, as
> does the time taken to check for files installed by multiple packages.
> Furthermore, we get false positives where a file is reported as being
> installed by multiple copies of the same package.
>
> With this approach we may end up with orphaned files in the target
> filesystem if a package that has been updated and rebuilt no longer
> installs the same set of files, but we know that only a clean build will
> produce reliable results. In fact it may be helpful to identify these
> orphaned files as evidence that the build is not clean.
