I also remember booting PDP 11/44's in which you had to type into the console some magic octal numbers to get it to read the boot block. There was a single digit difference between the incantation to "read" the block and to "write" it :). Kids today, they're spoilt. In my day there was none of this new-fangled fsck nonsense; we were real system manager in those days, "clri" was our friend. And then that wonderful moment when after repairing the root file system for 30 minutes you typed "sync" before rebooting - and you got the wonderful learning opportunity of doing it all over again :) I do remember the early versions of fsck, one day we let it rip and auto-repair one of the file-systems, it took a long time. We had a beautifully clean system at the end of it though, it had systematically removed every single file on the system. -- Regards Cliff Sarginson -- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
