Hoi Net, We have a DEC station 2100 as a client attached to a server DEC system 5400. Via the Diskless Management System the clients are configured to boot their kernel of the /dlclient?/CLIENT.root area. The DMS manual shows how to modify the configuration so that a local disk can be used as swap. The I am wondering if it is possible to change the configuration of a client DECstation (2100) with one local disk (RZ23), so that not only the swap space is local but also its root filesystem. (servers is then only needed for the clients /usr's file system.) It seems a possible modifications reading the DMS manual (appendix A. netblk.c ) But nothing clear is stated about root on local disk. I tried it, by doing the following steps. 1) Configure a Kernel with partial swap on local disk. Made filesystems on the local disk. 2) Configure a kernel with partial swap on local disk and root on local disk. 3) Copied the server:/dlclient?/CLIENT file hierarchy to the local disk. 4) Try to boot from the local disk: boot -f rz(0,2,2)vmunix.test (I am certain about the boot command, because all other combinations result in the message that there is no boot block on the device.) This results in a responds like: Can't open Ultrixboot ! so copied a ultrixboot file on the local disk, but the error message is the same ! Does any body know if this is the right way to go ? Things I can think of that matter are the place of ultrixboot file. In the server e.g. it is the 6th ino entry of the root dir. In the client the ultrixboot file is the 290th ino. Something else is that the ultrixboot file is hardware dependent (disk type). Some clues would be welcome !

RIS is designed specifically to do what you are asking by making the client's root and swap area local. See your manuals for details. Later, Dan Heath dan@garfield.catt.ncsu.edu
