The problem is, most Debian systems are set up to mount the core file systems with "relatime". This means you don't have a record of the last time each file was accessed, so you can't ask the computer which files were most recently opened.
hm...i was curious about that and read the man page for 'mount(8)', in section FILESYSTEM-INDEPENDENT MOUNT OPTIONS i found the following:
relatime
Update inode access times relative to modify or change time.
Access time is only updated if the previous access time was
earlier than the current modify or change time. [...]
so my understanding is, that access time is indeed updated if 'relatime' is
used as a mount option. to prevent updating access times 'noatime' should
be used.
i am happy to be corrected if i should be wrong...
