RPM II

Plan:

Next steps:

example buildinfo files at https://buildinfo.debian.net/

to be run at the end of rpmbuild or after it, run by the tool calling rpmbuild or both (second one appending extra information)

buildinfo generator code snippet:

echo Installed-Build-Depends:
# might need to run outside the build chroot, because it might have an incompatible rpm version that cannot read the DB created by a newer rpm
rpm -qa | sed -e 's/-\([^-]*-[^-]*\)\.\([^.]*\)$/:\2 (= \1)/; s/^/ /'
#                      ver   rel        arch
echo Environment:
for var in LANG LC_ALL SOURCE_DATE_EPOCH ; do
  eval value=\$$var
  [ -n "$value" ] && echo " $var=\"$value\""
done
# whitelist in dpkg: [https://anonscm.debian.org/git/dpkg/dpkg.git/tree/scripts/Dpkg/Build/Info.pm#n50](https://anonscm.debian.org/git/dpkg/dpkg.git/tree/scripts/Dpkg/Build/Info.pm#n50)

function getos
{
  test -r /etc/os-release && . /etc/os-release
  if [ -z "$ID" ] ; then
    ID=$(cat /etc/system-release)
  fi
  echo "$ID"
}
echo "Build-Origin: $(getos)"
echo "Build-Date: `date -R`" # - not from rpm because that will be $SOURCE_DATE_EPOCH



libc6:i386 (= 2.24)
libgcc:x86_64 (= 4.4.7-17.el6)

Checksum-*: ... sha256sum $rpm $specfile $srcrpm # and rpm size # omit MD5+SHA1 because nobody should use that anymore
