guix shell -m manifest.scm
 
Voilà, you've converted a long command line into a manifest! That conversion process honors package transformation options (@pxref{Package Transformation Options}) so it should be lossless.
 
Create an environment containing the packages installed in @var{profile}. Use @command{guix package} (@pxref{Invoking guix package}) to create and manage profiles.
 
--pure
 
Unset existing environment variables when building the new environment, except those specified with @option{--preserve} (see below). This has the effect of creating an environment in which search paths only contain package inputs.
 
--preserve=@var{regexp}
 
-E @var{regexp}
 
When used alongside @option{--pure}, preserve the environment variables matching @var{regexp}---in other words, put them on a ``white list'' of environment variables that must be preserved. This option can be repeated several times.
 
guix shell --pure --preserve=^SLURM openmpi @dots{} \
-- mpirun @dots{}
 
This example runs @command{mpirun} in a context where the only environment variables defined are @env{PATH}, environment variables whose name starts with @samp{SLURM}, as well as the usual ``precious'' variables (@env{HOME}, @env{USER}, etc.).
 
--search-paths
 
Display the environment variable definitions that make up the environment.
 
Attempt to build for @var{system}---e.g., @code{i686-linux}.
 
--container
 
-C
 
container
container
Run @var{command} within an isolated container. The current working directory outside the container is mapped inside the container. Additionally, unless overridden with @option{--user}, a dummy home directory is created that matches the current user's home directory, and @file{/etc/passwd} is configured accordingly.
 
The spawned process runs as the current user outside the container. Inside the container, it has the same UID and GID as the current user, unless @option{--user} is passed (see below).
 
--network
 
For containers, share the network namespace with the host system. Containers created without this flag only have access to the loopback device.
 
--link-profile
 
-P
 
For containers, link the environment profile to @file{~/.guix-profile} within the container and set @code{GUIX_ENVIRONMENT} to that. This is equivalent to making @file{~/.guix-profile} a symlink to the actual profile within the container. Linking will fail and abort the environment if the directory already exists, which will certainly be the case if @command{guix shell} was invoked in the user's home directory.
 
Certain packages are configured to look in @file{~/.guix-profile} for configuration files and data;@footnote{For example, the @code{fontconfig} package inspects @file{~/.guix-profile/share/fonts} for additional fonts.} @option{--link-profile} allows these programs to behave as expected within the environment.
 
--user=@var{user}
 
-u @var{user}
 
For containers, use the username @var{user} in place of the current user. The generated @file{/etc/passwd} entry within the container will contain the name @var{user}, the home directory will be @file{/home/@var{user}}, and no user GECOS data will be copied. Furthermore, the UID and GID inside the container are 1000. @var{user} need not exist on the system.
 
Additionally, any shared or exposed path (see @option{--share} and @option{--expose} respectively) whose target is within the current user's home directory will be remapped relative to @file{/home/USER}; this includes the automatic mapping of the current working directory.
 
# will expose paths as /home/foo/wd, /home/foo/test, and /home/foo/target
cd $HOME/wd
guix shell --container --user=foo \
--expose=$HOME/test \
--expose=/tmp/target=$HOME/target
 
While this will limit the leaking of user identity through home paths and each of the user fields, this is only one useful component of a broader privacy/anonymity solution---not one in and of itself.
