+------
+  - "fstrim --fstab" uses root= from /proc/cmdline to get root FS when it's missing
+    in fstab file. This is fragile (due to missing root= or the root FS is not 
+    accessible). The best seems to parse mountinfo and use mnt_table_get_root_fs()
+    as a fallback solution.  https://github.com/karelzak/util-linux/issues/1266.
