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.
* guix/scripts/pack.scm (wrapped-package)<build>: Build wrappers for
executable files and symlink others.
* tests/guix-pack-relocatable.sh: Test relocatable example of mixed
executable and non-executable files.
* tests/guix-archive.sh, tests/guix-build-branch.sh, tests/guix-build.sh,
tests/guix-daemon.sh, tests/guix-download.sh, tests/guix-environment.sh,
tests/guix-gc.sh, tests/guix-git-authenticate.sh, tests/guix-graph.sh,
tests/guix-hash.sh, tests/guix-lint.sh, tests/guix-pack-relocatable.sh,
tests/guix-pack.sh, tests/guix-package-aliases.sh, tests/guix-package-net.sh,
tests/guix-package.sh: Use the shell '!' keyword to negate command exit status
in place of 'if ...; then false; else true; fi'
Previously it would silently fail to create the /gnu/store symlink when
the host has a read-only /gnu as is the case in these tests.
* gnu/packages/aux-files/run-in-namespace.c (exec_with_loader): Unlink
the ancestor of ORIGINAL_STORE under NEW_ROOT. Check the return value
of 'symlink' when creating NEW_STORE.
* tests/guix-pack-relocatable.sh: Check the contents of the store as
seen by the wrapped executable, with all three engines, and with both
"/gnu" and "/gnu/store" erased.
Fixes <https://bugs.gnu.org/42558>.
Until now, loading 'pack-audit.so' in a truly non-Guix environment would
usually fail because 'pack-audit.so' depends on 'libgcc_s.so' and
'libc.so', none of which could be found.
Furthermore, the test was not working as expected: the trick
unshare -mrf sh -c 'mount -t tmpfs none /gnu ; ...'
would allow the fakechroot engine to make its store available as
/gnu/store as a result of another bug.
* gnu/packages/aux-files/run-in-namespace.c (relocated_search_path): New
function.
