+Subject: [PATCH] Fix escaping issues when generating the OCI image config
+ files
+
+Some parameters are not escaping correctly the double quotes
+when generating the OCI image config files.
+
+This is easily reproducible:
+
+$ mkdir rootfs
+$ ./sloci-image --arch arm --user 0 rootfs oci-image:latest
+$ grep -R "User" oci-image/
+oci-image/blobs/sha256/e574ac66b91453b00beb37717ed0e604249fa695ec772e17a56ff208357ec72a:    \"User\": "0",
+
+Fix that by escaping the double quotes with an echo command.
