The documentation (info "(guix) Invoking guix system") phrases it this
way:

     The example below creates a VM in which the user=E2=80=99s home direct=
ory
     is accessible read-only, and where the =E2=80=98/exchange=E2=80=99 dir=
ectory is a
     read-write mapping of =E2=80=98$HOME/tmp=E2=80=99 on the host:

          guix system vm my-config.scm \
             --expose=3D$HOME --share=3D$HOME/tmp=3D/exchange

IOW, if you do =E2=80=9Ccd /exchange=E2=80=9D in the guest, you should see =
the contents
of the host=E2=80=99s $HOME/tmp, read-write.  Likewise, if $HOME =3D /foo i=
n the
host, then /foo in the guest is a read-only view of the host=E2=80=99s /foo.

HTH!
