Hi all, just a short status update of the things that are currently required to make polystrap - building debian rootfs without superuser permissions - fully work out-of-the-box.
1. fakechroot ------------- fakechroot is still having a bug where the root path gets prefixed twice in certain situations (when doing mknod and when using certain architectures like armhf). Unfortunately the maintainer seems to be MIA but I'm in touch with the debian-mia team about that and a NMU might follow: I reported and proposed a patch here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611156 2. qemu-user-static elf interpreter prefix ------------------------------------------ Currently, one has to fill the /etc/qemu-binfmt/* directories before executing any dynamically compiled foreign executable with fakeroot/fakechroot because there is no way to pass the -L parameter to qemu-user-static to specify the just extracted rootfs directory as the elf interpreter prefix path. Being able to do so by making it evaluate an environment variable instead, would be a huge improvement because it would make it possible to avoid changing the content of /etc/qemu-binfmt/* directories every time * one changes between debian architectures that use the same qemu emulation (eg. arm, armel and armhf all use qemu-arm) * one changes between different debian suites * shared library versions are outdated I reported and proposed a patch here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=632192 3. fakeroot/fakechroot multiarch -------------------------------- To execute code in a foreign rootfs with fakeroot/fakechroot, libfakechroot.so and libfakeroot-sysv.so need to be present in the appropriate /usr/lib/<arch-triplet>/ directory. Currently I copy those into it manually with dpkg -x. This problem should be solved by multiarch, right? Is it already possible? What is missing? 4. building for mips/mipsel --------------------------- This issue currently fails due to some bugs related to wrong syscall handling in qemu-mips. The effect is explained in these mails to the qemu-devel list: http://lists.gnu.org/archive/html/qemu-devel/2010-05/msg00116.html http://lists.gnu.org/archive/html/qemu-devel/2011-07/msg00102.html http://lists.gnu.org/archive/html/qemu-devel/2011-07/msg00340.html A patch that supposedly (did not yet test) solves the issue was posted just today: http://lists.gnu.org/archive/html/qemu-devel/2011-07/msg00313.html Once it is committed, building for mips/mipsel should work again. 5. tzdata --------- There is currently a bug in tzdata that is triggered when using debconf-set-selections before configuring the package. It can be avoided by not setting any tzdata values in debconfseed.txt. I did not find the time to look into why exactly that happens or to prepare a patch but given how quickly other recent similar issues were solved this will probably also be fixed soon. I reported and explained the issue here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611156 I hope I didnt forget anything. cheers, josch -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
