re-compiling
I have a problem.
How can I be sure that the binary currently in production is the binary originally produced by the compiler? I ask because recompiling the sources (ALL sources + stripping away the metadata: strip ...) does not give the same result.
I am pretty sure that I wasn't hacked!
Your comments to how this can happen and how to ensure a reproducible binary are highly appreciated.
Thanks
Frank

dpkg-scansources
dpkg-scansources(1) dpkg suite dpkg-scansources(1)
NAME
dpkg-scansources - create Sources index files
SYNOPSIS
dpkg-scansources [option...] binary-dir [override-file [path-prefix]] > Sources
DESCRIPTION
dpkg-scansources scans the given binary-dir for .dsc files. These are used to create a Debian source index, which is output to stdout.
The override-file, if given, is used to set priorities in the resulting index records and to override the maintainer field given in the
.dsc files. The file can be compressed (since dpkg 1.15.5). See deb-override(5) for the format of this file. Note: Since the override
file is indexed by binary, not source packages, there's a bit of a problem here. The current implementation uses the highest priority of
all the binary packages produced by a .dsc file for the priority of the source package, and the override entry for the first binary package
listed in the .dsc file to modify maintainer information. This might change.
The path-prefix, if given, is prepended to the directory field in the generated source index. You generally use this to make the directory
fields contain the path from the top of the Debian archive hierarchy.
Note: If you want to access the generated Sources file with apt(8) you will probably need to compress the file with gzip(1) (generating a
Sources.gz file). apt ignores uncompressed Sources files except on local access (i.e. file:// sources).
OPTIONS
-n, --no-sort
Don't sort the index records. Normally they are sorted by source package name.
-e, --extra-override file
Scan file to find supplementary overrides (since dpkg 1.15.4; the file can be compressed since dpkg 1.15.5). See deb-extra-override(5)
for more information on its format.
-s, --source-override file
Use file as the source override file (the file can be compressed since dpkg 1.15.5). The default is the name of the override file you
specified with .src appended.
The source override file is in a different format from the binary override file. It contains only two whitespace separated fields, the
first is the source package name and the second is the section. Blank lines and comment lines are ignored in the normal manner. If a
package appears in both files the source override takes precedence for setting the section.
--debug
Turn debugging on.
--help
Show the usage message and exit.
--version
Show the version and exit.
