As a result, the image will likely contain parts of deleted files from the host OS. This will reduce compressability of the disk images and may cause the disk images to contian sensitive information, such as passwords and credit card numbers. This isn't a problem unless you think you might possibly give the disk image to someone else in the future. To prevent this, in the dd command, use if=/dev/zero and change the count to be the suggested seek value. Do not specify a seek value. This will cause dd to take longer to create a disk image, but it will zero out the contents of the file, rather than asking the OS to create a file from whatever garbage is left on disk. As much as I like your passwords, credit card numbers, and assorted smutt, I'd rather not download them from Free OS Zoo. -Karl On Sat, 2 Oct 2004 15:16:21 +0200, albi wrote: > > hi, > > First of all, kudos for developing QEMU! it's cool to play with! :) > > I noticed an error at the downloads, when i downloaded reactos-0.2.3.tar.bz2 > i found out it's really a tar.gz file and not a tar.bz2, can you change that > ? thnx > > cya, > albi > > _______________________________________________ > Qemu-devel mailing list > Qemu-devel@nongnu.org > http://lists.nongnu.org/mailman/listinfo/qemu-devel >
