This is dangerous, because I sometimes forget un-protecting these media. Linux mount automatically adds read-only option, when mounting write protected media. This is safe... >How-To-Repeat: 1) mount write protected removable media. 2) write something this media. 3) un-mount this media. >Fix: How about adding read-only mount option automatically like Linux mount. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
