Reported by Jan (janneke) Nieuwenhuizen <janneke@gnu.org>. * gnu/packages/aux-files/run-in-namespace.c (main): In the 'default' case, check 'WIFEXITED (status)' and exit with the corresponding code in that case. Exit with 255 in other cases. * tests/guix-pack-relocatable.sh: Add test. 2019-08-23pack: '-R' honors the requested output.Ludovic Courtès Fixes <https://bugs.gnu.org/36925>. Reported by Jesse Gibbons <jgibbons2357@gmail.com>. * guix/scripts/pack.scm (wrapped-package): Add 'output*' parameter. [build]: Define 'input' and 'target'; use them instead of #$package and #$output, respectively. (wrapped-manifest-entry): New procedure. (map-manifest-entries): Call PROC directly. (guix-pack): Pass WRAPPED-MANIFEST-ENTRY to 'map-manifest-entries'. 2019-05-18pack: '--localstatedir' and '-R' tests gracefully handle missing /gnu/store.Ludovic Courtès Fixes <https://bugs.gnu.org/35776>.

Reported by Josh Holland <josh@inv.alid.pw>. * tests/guix-pack-relocatable.sh: Before invoking 'unshare' at the bottom, add "if unshare -r true" condition. * tests/guix-pack.sh: Likewise. 2019-03-15pack: "-RR" produces PRoot-enabled relocatable binaries.Ludovic Courtès * gnu/packages/aux-files/run-in-namespace.c (exec_with_proot): New function. (main): When 'clone' fails, call 'rm_rf'. [PROOT_PROGRAM]: When 'clone' fails, call 'exec_with_proot'. * guix/scripts/pack.scm (wrapped-package): Add #:proot?. [proot]: New procedure. [build]: Compile with -DPROOT_PROGRAM when PROOT? is true. * guix/scripts/pack.scm (%options): Set the 'relocatable?' value to 'proot when "-R" is passed several times.
