+Another typical use case for containers is to run security-sensitive
+applications such as a web browser.  To run Eolie, we must expose and
+share some files and directories; we include @code{nss-certs} and expose
+@file{/etc/sll/certs/} for HTTPS authentication; finally we use
+@code{env} from the @code{coreutils} package to set the @code{DISPLAY}
+environment variable since containerized graphical applications won't
