| |
(lkml readers: this concerns a security issue reported to debian by a user of udev/aacraid. udev gives the aacraid devices the floppy group because it reports block devices as 'removable'. See http://bugs.debian.org/404927 for the entire thread).

Ok, let's ask lkml

I didn't turn up any otherwise when I was grepping yesterday, but my search terms may have been too naive. I also checked a machine I had w/ cciss - it did not have the removable flag set.
I found a message from Mark Salyzyn from last year that suggested this was more pervasive: http://www.ussg.iu.edu/hypermail/linux/kernel/0602.2/1231.html Mark: Can you identify some of these other drivers?
