Any metrics? The syscons scrollback buffer is _not_ the kernel message buffer. Syscons scrollback buffer is quite small (about 96 lines IIRC), while the kernel message buffer is something like 8K by default. Increasing the kernel message buffer will not give you more scrollback. If you just want to increase the scrollback buffer, set SC_HISTORY_SIZE to something obscenely large like 500 (memory penalty for all vtys) or alternatively set MSGBUF_SIZE to something like 32K (only eats that much more memory) and add the ability to view it inside sysinstall. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
