Package: coreutils
Version: 5.2.1-2
Severity: wishlist
dd should either always use O_DIRECT for reading and writing, or it should
allow one to set it as an option. /dev/raw is deprecated, and many dd uses
really are a prime candidate for O_DIRECT.
Examples of stuff that waste a tremendous ammount of VM due to dd's lack of
O_DIRECT behaviour:
dd if=/dev/zero of=(disk block device)
dd if=file of=(disk, tape or cd/dvdrom block device in packet writing
mode)
dd if=(one block device) of=(other block device) with disks.
