Sorry, this is my mistake, -E is run after each slice created, this is
-F that should be used here for your commands to be run before each
slice to be read.

for dar:
-F is associated with the archive of reference (-A option) while -E is
associated to the archive object of the operation in dar ( -c -x -t -d
... options).

By similarity, for dar_xform, -F is for the read archive and -E for the
written one.

Cheers,
Denis
