While it's true that this was the case for workstations, where you would end up having 128 workstations and 128 copies of the / directory on the server for the diskless/dataless workstations, I think the R/W mount was out of necesssity, not out of desirability. For most of the work I've done over the past 5/6 years, it's really desirable to have / mounted read-only. > > the 'original' solution is to make /etc writable is to mount a MD, then copy > > all > > /conf/default/etc to it. > > The very original "solution" was to mount NFS / RW.

This isn't just about NFS... it's also about Fash devices, which are only warranteed for a limited number of writes, which mounting R/W would really eat into, and it's for read-only media, like in the "ClosedBSD" and "PicoBSD" FreeBSD based firewalls, I think. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
