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

     The example below creates a VM in which the user’s home directory
     is accessible read-only, and where the ‘/exchange’ directory is a
     read-write mapping of ‘$HOME/tmp’ on the host:

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

IOW, if you do “cd /exchange” in the guest, you should see the contents
of the host’s $HOME/tmp, read-write.  Likewise, if $HOME = /foo in the
host, then /foo in the guest is a read-only view of the host’s /foo.

HTH!
