(Noticed when running a diskless system; at one point /etc/rc tries to copy /tmp/xxxx to /etc/motd, and /tmp is itself a null mount of /var/tmp, and this fails) >How-To-Repeat: # mkdir /a /b /c # mount_null /b /c # echo wibble >/c/stuff # cp /c/stuff /a cp: /a/stuff: Bad address # >Fix: No idea >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
