74fe2114cdc7e937ba8bd2'>pack: Relocatable wrapper leaves root available to child processes....Fixes <https://bugs.gnu.org/44261>. Reported by Jan Nieuwenhuizen <janneke@gnu.org>. * gnu/packages/aux-files/run-in-namespace.c (exec_in_user_namespace): Add call to 'prctl'. Call 'mount' for NEW_ROOT and define 'is_tmpfs'. When IS_TMPFS is true, call 'umount' and 'rmdir' after 'waitpid'; otherwise, call 'rm_rf' only when 'waitpid' returns -1 the second time. (exec_with_loader): Call 'prctl'. Remove NEW_ROOT only when 'waitpid' returns -1 the second time, otherwise leave it behind. * tests/guix-pack-relocatable.sh (wait_for_file): New function. Add test. Ludovic Courtès 2020-10-30guix: pack: Fix offset calculation for store directory mount point....Fixes wrapping of non-package things, where the target store directory may differ in length from the original. * guix/scripts/pack.scm (wrapped-package)<build-wrapper>: Define WRAPPER_PROGRAM macro with wrapper's file name. * gnu/packages/aux-files/run-in-namespace.c (main): Offset index by len of that file name. Eric Bavier 2020-08-27pack: fakechroot: Honor $LD_LIBRARY_PATH....Until now, when using the "fakechroot" engine, $LD_LIBRARY_PATH would always be ignored. However, it's useful in some cases to allow users to specify LD_LIBRARY_PATH, so honor it. * gnu/packages/aux-files/run-in-namespace.c (concat_paths): New function. (exec_with_loader): Concatenante $LD_LIBRARY_PATH to the relocated AUDIT_LIBRARY_PATH. Ludovic Courtès
