Sure. The problem is just implementing any persistence at all. Consider that we support the following backing-stores for the kernel: - UFS on local disk - (V)FAT(32) - NFS - TFTP - iso9660 Obviously we can't write to CDROMs, but a persistence mechanism needs to work with each of these others. I've been leaning towards a very simple solution using a small, preallocated file which we just overwrite. It's not beautiful, but it's workable. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
