Previously the order of the options giving to 'guix shell' could mean that the
'glibc-for-fhs' package included with the '--emulate-fhs' option would not
appear in the container. For example, using the development option with a
package using the 'gnu-build-system', e.g. 'guix shell -CFD hello', would
include the regular 'glibc' package. The option ordered mattered: 'guix shell
-CD hello -F' would include the expected 'glibc-for-fhs'. We fix this by
having 'glibc-for-fhs' added to the package list just before calling
'options-with-caching' so the option order given by the user does not matter.
* guix/scripts/shell.scm (%options): Move the '--emulate-fhs' (expression
. ...) component from here...
(parse-args): ... to here.
* tests/guix-environment-container.sh: Add a test to check that
'glibc-for-fhs' is in the container even when 'glibc' is included in the 'guix
shell' package list.

Previously, using 'guix shell -CF coreutils' twice (such that the
profile is cache) would result in:
guix shell: error: '--profile' cannot be used with package options
This patch fixes it by moving argument handling to (guix scripts shell),
before 'options-with-caching' is called.
* guix/scripts/environment.scm (show-environment-options-help)
(%options): Remove '--emulate-fhs'.
(guix-environment*): Pass OPTS as-is to 'options/resolve-packages'.
* guix/scripts/shell.scm (show-help, %options): Add '--emulate-fhs'.
Add the (expression . ...) component to RESULT right from the argument
handler.
* tests/guix-environment-container.sh: Change '--emulate-fhs' tests to
use 'guix shell' instead of 'guix environment'.
* guix/scripts/environment.scm (show-environment-options-help, %options): Add
'--emulate-fhs'.
(setup-fhs): New procedure. Setup for the Filesystem Hierarchy Standard (FHS)
container. Defines and uses FHS-SYMLINKS and LINK-CONTENTS to create FHS
expected directories and creates /etc/ld.so.conf.
(launch-environment): Add 'emulate-fhs?' key and implement it to set $PATH and
generate /etc/ld.so.cache before calling COMMAND.
(launch-environment/container): Add 'emulate-fhs?' and 'setup-hook' keys and
implement them. Define and use FHS-MAPPINGS, to set up additional bind mounts
in the container to follow FHS expectations.
(guix-environment*): Add glibc-for-fhs to the container packages when
'emulate-fhs?' key is in OPTS.
* doc/guix.texi (Invoking guix shell): Document '--emulate-fhs'.
(Invoking guix environment): Document '--emulate-fhs'.
* tests/guix-environment-container.sh: Add tests for '--emulate-fhs'.

This is a followup to 0f53c801b9.
* guix/scripts/environment.scm (launch-environment/container): Add call
to 'set-network-interface-up'.
* tests/guix-environment-container.sh: Add test.
This test was skipped since the switch to Guile 3 because
'assert-container-features' would be inlined and thus accessing it with
@@ would fail with an unbound-variable error.
* guix/scripts/environment.scm (assert-container-features): Export.
* tests/guix-environment-container.sh: Use single '@'.
This ensures that this test is skipped in contexts where user namespaces
are not supported, instead of failing.
This is a followup to commit b6dc08393e.
* tests/guix-environment.sh: Move '--container --no-cwd' test to...
* tests/guix-environment-container.sh: ... here.
* guix/scripts/environment.scm (launch-environment/container): Add UID
and GID. Use them in PASSWD and GROUPS. Pass them as #:guest-uid and
#:guest-gid to 'call-with-container'.
* tests/guix-environment-container.sh: Test the inner UID.
In '--user' test, replace hard-coded 0 with 1000.
* doc/guix.texi (Invoking guix environment): Adjust accordingly.
Reported by Pierre Neidhardt <mail@ambrevar.xyz>.
* guix/scripts/environment.scm (launch-environment/container): Create
GROUPS and call 'write-group'.
* tests/guix-environment-container.sh: Test it.
* guix/scripts/environment.scm (launch-environment/container): Remove
call to 'mock-passwd'; instantiate a <password-entry> instead. Call
'write-passwd' to write the pasword database instead of using custom
code.
(mock-passwd): Remove.
* tests/guix-environment-container.sh: Test 'getpwuid'.
This change allows overriding the home directory of all filesystem mappings to
help hide the identity of the calling user in a container.
* doc/guix.texi (Invoking guix environment)[--container]: Mention --user.
[--user]: Add item.
* guix/scripts/environment.scm (show-help): Add --user.
(%options): Add --user.
(launch-environment/container) Add 'user' parameter. Update doc. Override
'user-mappings' using 'override-user-mappings'. Consider override for chdir.
(mock-passwd, user-override-home, overrid-euser-dir): New procedures.
(guix-environment): Disallow --user without --container. Provide user to
'launch-environment/container'.
* tests/guix-environment.sh: Add user test.

This change is motivated by attempts to run programs (like GNU IceCat) within
containers. The 'fontconfig' program, for example, is configured explicitly
to check ~/.guix-profile for additional fonts.
There were no existing container tests in 'tests/guix-environment.sh', but I
added one anyway for this change.
* doc/guix.texi (Invoking guix environment): Add '--link-profile'.
* guix/scripts/environment.scm (show-help): Add '--link-profile'.
(%options): Add 'link-profile' as '#\P', assigned to 'link-profile?'.
(link-environment): New procedure.
(launch-environment/container): Use it when 'link-profile?'.
[link-profile?]: New parameter.
(guix-environment): Leave when '--link-prof' but not '--container'. Add
'#:link-profile?' argument to 'launch-environment/container' application.
* tests/guix-environment-container.sh: New '--link-profile' test.

Switching to execlp means that the process spawned in a container is PID
1, which obsoleted one of the 'guix environment --container' tests
because the init process can't be killed in the usual manner.

(launch-environment): Switch from system* to execlp. Add handler for
SIGINT.
(guix-environment): Use launch-environment/fork.

one that works now that the spawned process is PID 1.
