+  [ Steve Langasek ]
+  * scripts/plugininstall.py: don't hard-code a resume partition in
+    /etc/initramfs-tools/conf.d/resume at install time.  In bionic and later,
+    initramfs-tools will autodetect an appropriate resume partition at
+    initramfs generation time, so ubiquity's resume setting is redundant and
+    possibly wrong.  LP: #1768230.
