+# By default sytemd uses it's build time as epoch. This causes problems when
+# using yocto cache since systemd build time might be more than day older than
+# the actual image build time. If that kind of image is booted with a device
+# that does not have backup battery for RTC, the first fsck interprets successful
+# result as failure because last mount time is in the future. This can be worked
