Under normal udev operation, device nodes are obviously timestamped
based on the system time at current boot. However, when using
udev-cache, they are timestamped from a previous boot.
The existence of machines lacking RTCs makes this more than a cosmetic
issue: if the current time is set further on in the boot, so that the
system time is still 1970 by the time the cache is extracted, tar will
print a timestamp warning for every extracted file (potentially hundreds
of them).
To fix, use -m on extract.
If using busybox `tar`, this commit requires
CONFIG_FEATURE_TAR_NOPRESERVE_TIME=y.
