[erlang-questions] Best way to check if a given directory is empty (or not)?

You need to be careful with things like /atime/ - systems using solid
state disks tend to routinely set the /noatime /flag to minimise the
number of write-cycles the disk undergoes, which on SSDs limit the
lifetime of the disk.
I strongly suspect that the link count from file:read_file_info() (as in
Taavi's post) is the way forward.
