Description:
At least for desktops, we should reduce the memory and I/O thrash
caused by atime updates, by using relatime.

Bug #461829 is not requesting breaking POSIX semantics by default!
relatime should replace noatime option in the mount options part of
partioner tool, especially now it has been improved to update atime on
file access if it's older than 24 hours.
Standards are important, and LRU file caches cannot be relied on if
noatime usage is common, or if poor backup software touches atimes,
when reading files.
