--- Begin Message ---Package: fakechroot Version: 2.17.2-1 Severity: minor Tags: patch Dear Maintainer, In a fakechroot environment, invoking chroot twice gives some strange results : 1/ absolute paths for newroot cause an error $ fakechroot fakeroot chroot my_first_chroot # cd home # chroot /home/me/my_second_chroot ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded: ignored. ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded: ignored. $ echo $LD_LIBRARY_PATH /home/me/my_first_chroot/home/me/my_second_chroot/usr/lib:/home/me/my_first_chroot/home/me/my_second_chroot/lib (the path of libfakeroot disappeared) or $ fakechroot fakeroot chroot my_first_chroot # chroot . /usr/sbin/chroot: cannot change root directory to : No such file or directory 2/ relative paths for newroot are followed, but : a/ non existent paths are added to LD_LIBRARY_PATH $ fakechroot fakeroot chroot my_first_chroot # chroot home/me/my_second_chroot The output of # echo $LD_LIBRARY_PATH is attached (LD_LIBRARY_PATH.1). Paths "/home/me/my_first_chroot/home/me/my_first_chroot/home/me/my_second_chroot/home/me/my_first_chroot/*" don't exist. FAKECHROOT_BASE_ORIG (ie /home/me/my_first_chroot) is added twice to the components of LD_LIBRARY_PATH, and kept after newroot. b/ paths inside the previous (fake)chroot are kept in LD_LIBRARY_PATH. They would be forgotten in a real chroot. What is the correct policy for fakechroot ? In the previous example, do we have to keep /home/me/my_first_chroot/usr/lib/x86_64-linux-gnu/libfakeroot: /home/me/my_first_chroot/usr/lib64/libfakeroot: /home/me/my_first_chroot/usr/lib32/libfakeroot: /home/me/my_first_chroot/usr/local/lib: /home/me/my_first_chroot/lib/x86_64-linux-gnu: /home/me/my_first_chroot/usr/lib/x86_64-linux-gnu in LD_LIBRARY_PATH ?
