Identifier:
|
user_hostname_manually_added_requiring_further_investigation
|
Description
|
Packages which intentionally capture the username or hostname into a custom format, but aren't obviously using any tool or system which has this as a core issue. Interesting because they could be fixed by fixing these things at build time.

Identifier:

captures_home_dir
|
Description
|
Captures home directory, e.g., first-build v. second-build.
|
Identifier:
|
captures_kernel_version
|
Description
|
Stores the kernel version (uname -a, /proc/version, etc.) output, normally for debugging purposes. . Sub-issue: captures_kernel_version_via_CMAKE_SYSTEM
|
Identifier:
|
captures_users_gecos
|
Description
|
Captures user's GECOS, e.g., second room. . Sub-issue texi2html_captures_users_gecos

Identifier:
|
leaks_path_environment_variable
|
Description
|
The environment variable PATH is embedded in the build result. Sometimes it's just leaked into some file (so "just" causing reproducibility issues), while sometimes this PATH is also used for building, which might give unexpected and broken results.

Identifier:
|
records_build_flags
|
Description
|
Records $CFLAGS, which vary intentionally due to the «-fdebug-prefix-map=${BUILDPATH}=.», «-ffile-prefix-map=${BUILDPATH}=.» or «-fmacro-prefix-map=${BUILDPATH}=.» flags. . We have a patch pending to GCC to fix this issue centrally: . https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00182.html . Though the patch is currently unlikely to be merged. If/when this is accepted, this issue should be fixed for all packages and you should not need to fix it specifically in your package. . There is also a work-in-progress patch to dpkg that could address this issue: . https://bugs.debian.org/985553 .

dtrace generates C source files in a random temporary location. https://sources.debian.net/src/systemtap/2.9-3/dtrace.in/#L413 https://sources.debian.net/src/php7.0/7.0.4-6/acinclude.m4/?hl=2993,2998#L2993 This temporary filename leaks into debug information and causes a build id variation.
