Up there on my wish list is getting a journaling > filesystem ported to FreeBSD. It's not system call but `od' driver does check if the medium is writable or not. It returns EACCESS when the mount option is -rw and the medium is read-only. `od' is drived from `da' so quick hack will do the trick. ftp://daemon.jp.FreeBSD.org/pub/FreeBSD-jp/OD/ // Noriaki Mitsunaga // To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
