Because believe it > or not, people make mistakes. Then you are right back to breaking scripts. And yes, people make mistakes... and unix *lets* them. You don't see rm stopping every time you try to delete a file and saying really? *That* file? Are you sure? You don't see dd or shell redirection stopping to ask you if you really meant to overwrite that disk or file. There is a *reason* why you are supposed to double check commands you are running as root. And putting a filesystem in an image file is one of the *least* dangerous things you could do. Of all of the things to second guess, and especially to default to "HALT! ERROR!" behavior, this has to be the silliest. If you can't assume that an interactive user knows what they are doing and meant what they said, then at least you should assume that a script writer knows wtf they are doing without asking them to add lots of silly --yes-i-know-what-im-doing-stop-annoying-me flags. > Agreed, but it should not be lifted, but rather changes to check > for signatures on the device. The same way as it is done for > example in xfs, or btrfs. *NO*! Those tools annoy the hell out of me because they do that. I *know* there is another filesystem there already ( as there are on most disks not fresh from the factory ), why do you think I'm telling you to change it? Do what I asked and stop treating me like a child. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTKZ0fAAoJEI5FoCIzSKrwaFQH/RO0NPl2mPAlpaK2YQysegub u80nYpSlpHjiIOLU7RCECakfELIFp1skg7lRsFdL1zLNkor4JkwW8UbOuy75WbS3 +XPAQ/1wxPzsn0J4+QM3PE3X/IZ4NWRMepl0pozpoLine87mL6u6+em2n1r1vsQK HE/1Ma/8jqPPMXPNFDw0LMiYGyAHITfQA4c/FRwlWCbhMt2lG8dsGA7bKl7VCB5D gmkzUF/KbgmY8xnDiIbmSHQbaF+xrIbZl8FGgi4r3CuiGZ2yZBBbs2sTCk6pvIq7 rrTQGwxBuzxaas2h+ZpLfTeFulBlIH2B+ueStinc2Br+TmBeqIKKOQ1+HjO3v6g= =6eGY -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
