debian/rules文件是debian打包脚本中的核心文件，规定了debian对upstream 项目进行配置、编译、安装一系列的动作。下面，主要是通过code example来学习下众多的rule case.
export PYBUILD_NAME=tpm2-pkcs11-tools
export PYBUILD_DIR=$(CURDIR)/tools
D=$(CURDIR)/debian
D_PY=$D/python3-tpm2-pkcs11-tools
D_TOOLS=$D/libtpm2-pkcs11-tools
export DEB_LDFLAGS_MAINT_APPEND=-Wl,-z,now
override_dh_auto_configure:
dh_auto_configure -- --enable-unit
override_dh_auto_build-indep:
dh_auto_build --buildsystem pybuild
override_dh_auto_install-indep:
dh_auto_install --buildsystem pybuild
mkdir -p -- '${D_TOOLS}/usr/bin'
mv -- '${D_PY}/usr/bin/tpm2_ptool' '${D_TOOLS}/usr/bin/'
rmdir -- '${D_PY}/usr/bin'
%:
dh $@ --exclude=.la --exclude=.pc
其中， $(CURDIR)默认是Debian的临时编译文件存放的目录，这里可以灵活修改自己想要掌控的目录。
全局的针对编译系统的一个变量是DEB_LDFLAGS_MAINT_APPEND,或者还有CFLAGS，这里有一个wiki专门介绍了这点。
override_dh_auto_configure:
dh_auto_configure -- --enable-unit
指定运行配置项，这也是一个需要注意的地方。
debmake-doc 这里有一个更详细的编译顺序。
The current directory is set as: $(CURDIR)=/path/to/package-version/
DESTDIR=debian/binarypackage/ (single binary package)
DESTDIR=debian/tmp/ (multi binary package)
其中的DESTDIR是和Makefile的安装路径一起配合使用的。
dh是一个来自debhelper包的辅助命令，如下：
dh clean : clean files in the source tree.
dh build : build the source tree
dh build-arch : build the source tree for architecture dependent packages
dh build-indep : build the source tree for architecture independent packages
dh install : install the binary files to $(DESTDIR)
dh install-arch : install the binary files to $(DESTDIR) for architecture dependent packages
dh install-indep : install the binary files to $(DESTDIR) for architecture independent packages
dh binary : generate the deb file
dh binary-arch : generate the deb file for architecture dependent packages
dh binary-indep : generate the deb file for architecture independent packages
备注： For debhelper “compat >= 9”, the dh command exports compiler flags (CFLAGS, CXXFLAGS, FFLAGS, CPPFLAGS and LDFLAGS) with values as returned by dpkg-buildflags if they are not set previously. (The dh command calls set_buildflags defined in the Debian::Debhelper::Dh_Lib module.)
override_dh_auto_configure:
# Rebuild ./configure to get build system patches working
aclocal
autoconf
# --with-error-policy=retry-job # Set default job error policy to "retry-job", since it is less confusing and a better default on most machines
# --enable-sync-on-close # Set SyncOnClose to yes; considered saner on Linux
# --with-max-log-size=0 # Deactivate CUPS' internal logrotating, as we provide a better one, especially LogLevel debug2 gets usable now
dh_auto_configure -- \
$(CUPS_CONFIGURE_DISTRO_OPTIONS) \
--with-docdir=/usr/share/cups/doc-root \
--localedir=/usr/share/cups/locale \
...
这个片段来自cup. 可以重新configure,然后重点看下配置项是怎么添加进去的。
override_dh_auto_build:
dh_auto_build -- "`dpkg-buildflags --export=configure`"
override_dh_auto_install:
make install DESTDIR=debian/dds2tar
自定义安装的目录，这里需要看下Makefile的支持情况。
override_dh_installman:
rm -rf debian/dds2tar/usr/share/man/man1
dh_installman
适时的调整man手册。
这里的cases，是指遇到一些较为容易理解，自己之前没有遇到过的规则，现在总结下来，方便后面的使用。
这篇文章记录NMU。
RFS: electrum/4.3.2-0.1 [NMU] [RC] -- Easy to use Bitcoin client

Generally speaking, if others DD NMUed your package(s), you have to acknowledge this num in your next upload.
You should incorporate the changes from the NMU first.
Something like this:
$ dget https://deb.debian.org/debian/pool/main/j/jimtcl/jimtcl_0.82-4.1.dsc
change directory to your jimtcl repository:
$ cd jimtcl/
import the .dsc:
$ gbp import-dsc ../jimtcl_0.82-4.1.dsc

该问题的thread在mail list。基本情况是，由于之前手动安装某个package(python),导致引发了setuptools的bug:

在肥猫老师的帮助下，这个问题很快解决了，主要是通过这个命令:
strace -eopenat python -c "from importlib.metadata import entry_points; print(entry_points(group='sphinx.builders'))"
这里的一个新鲜事物是strace,之前有用过这个命令，但是没想到还可以用在这里。这是这个bug带来的最大收获。其次，为什么这里可以通过entry_points找到触发问题的入口呢？这是我目前不理解的地方。
这里的引入新包，是指Debian中并没有，而是从头开始创建。

参考 http://marquiz.github.io/git-buildpackage-rpm/gbp.import.html
还要注意repackage的问题:
$ gbp pq import
$ git checkout debian/master
$ gbp import-orig --pristine-tar --uscan
别忘记:
$ gbp pq rebase
$ gbp pq export
Once you’ve built and uploaded your package, you should tag the release.
$ gbp buildpackage --git-tag-only
$ git push --tags
arch 一般为 all(架构独立), 只有C扩展的才是any(架构非独立)
测试一般使用pytest或者unittest(unitetest应该就是默认的)

Debian python team的RFS有一些特殊的地方是，你除了发邮件外，还可以使用一些特殊手段在IRC发出请求提供帮助，那就是这样：
# on #debian-python channel
!rfs ueberzug
# remove rfs
!rfs -git-multimail
这样就可以的了。
这里，主要记载一些我自己upload的python包或者看到的一些好的打包范例。
lazy-loader 是我第一个比较打包顺利的python包，其中确实学到了不少的知识。尤其关注 2022-10 的debian python mail list对这个的初版审评意见。
pygubu这个包同 tkcanlendar一样，用到了 X11的环境。当然，这几个文件都需要仔细看看d/rules d/tests.
