comment What's faster, dd 1.5TB or rsync 500GB?
It also makes sense that, if the disk were full (1.5TB of actual non-sparse data), rsync would be slower than dd.

My buddy kormoc tells me: "kernel <-> userspace is just memory copies. It copies way faster then the disk actually responds, so it's almost free. DD still does the kernel -> user -> kernel layer changes as well. dd does not run in kernel space."

Awesome, thanks! For some reason I thought moving data between kernel-space and user-space was expensive, and dd avoids this, but I might be making that up.

comment Are multiple @daily crontab entries processed in order, serially?
@daily is slightly different than /etc/cron.daily. The former is an alternate syntax for use in a crontab. Also have a look at run-parts. My system uses run-parts to run programs in /etc/cron.daily. According to the run-parts(8) manpage, "Files are run in the lexical sort order of their names...".

@jw013 and Kevin: agreed, but that's not my question.

This helps, thanks. I agree @jw013's suggestion is valid, but that's not the question I asked. I guess I'll have to consult the actual source for the definitive answer, since this is probably, indeed, implementation-specific.
