There is life in operating systems (Unix in particular - FreeBSd included) beyond filesystems. Raw devices are being used, heavily for many things, including most commercial RDBMS. Also, filesystems are on the horizon (AFA FreeBSD is concerned) that can grow and for these one needs a storage medium that can grow. I do not find extendible storage all that useful, but i do not routinely maintain large servers that run out of space in the middle of everything either. ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.799.2313 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
