Would it be possible to export and mount /dev with rw options to a specific client? Or, more radical, if the roots of the clients end up being mounted RW eventually anyway, why not specify 'rw' in the lilo option? It's not like it is a local filesystem that may be corrupt where one should boot from it RO until it is checked... But I've never tried either approach, so it's really only an idea/possibility. Hope something works....the booting with a local initrd seems like it would be a pain... good luck, Linda Frank Steiner wrote: > Dick Streefland wrote: > >> Frank Steiner wrote: >> | Or is there any other way to get an initial console or >> | output any messages from an init script if one boots via nfsroot >> | and / (and thus, /dev) is only exported read-only from the >> | server? >> >> You can boot with a ramdisk as root, initialized with an initrd, and >> then perform all NFS mounts manually in the init script.
