 Python, GNU Coreutils, and glib.
 While these testsuites were written mostly to track regressions in the respective packages,
 some of the tests fail on the Hurd in general.

+# Open Issues
+
+`threads = yes` is set in `debian/sysdeps/linux.mk` and
+`debian/sysdeps/kfreebsd.mk`, `debian/sysdeps/hurd.mk` set to `no`.  But this
+is only read in `debian/rules` for deciding some `nscd` package issue?
+
+`debian/sysdeps/hurd.mk`'s `libc_extra_install` for `ld.so`: check with GCC
+configuration.
+
+Could add a toggle to `$(stamp)build_%` in `debian/rules.d/build.mk` to skip
+locale stuff.
+
+`--disable-compatible-utmp`?
+
+
+# Building
+
+Run `debian/rules patch` to apply patches (instead of having it done during the
+build).  Then you can edit files manually.
+
+Several passes: `libc`, `i686`, `xen`; `EGLIBC_PASSES='libc i686'`, etc.
+
+If building with `EGLIBC_PASSES=libc` (more specifically, without `xen`), the
+`libc0.3-dev_extra_pkg_install` rule in `debian/sysdeps/hurd-i386.mk` will
+fail.  (Same for `libc6-dev_extra_pkg_install` in `debian/sysdeps/i386.mk`, for
+example.)  Why is this special handling only done for `xen`, but not for
+`i686`?
+
+Do `export LC_ALL=C` before building, otherwise the testsuite/make error
+messages will be different from those stored in the
+`debian/testsuite-checking/expected-results-*` files.
+
+Run `debian/rules build-arch DEB_BUILD_OPTIONS=parallel=2 [EGLIBC_PASSES=...]`.
+Can stop with `C-c` during locale stuff or testsuite if only interested in the
+build tree.
