hiyas, I have two boxes here - one is a P90 (fatso) and another is a Celeron 667 (balance). ()s indicate the machine names. I wish to build kernel & world on balance and then NFS mount /usr/src and /usr/obj over to fatso so that it can install kernel & world. I tried to setup amd on fatso to automount /usr/src and /usr/obj as required - so that I could just do "cd /usr/src; make installkernel KERNCONF=FATSO" and it would automount /usr/obj as required (coz I am lazy to mount both /usr/src and /usr/obj manually :). The NFS exports are setup correctly on balance - I can mount them manually, and amd can mount them too. I start amd using: amd -p -a /.amd_mnt -l syslog /net /etc/amd.map And my /etc/amd.map reads: /defaults type:=nfs;rhost:=balance usr.src rfs:=/usr/src;fs:=/usr/src usr.obj rfs:=/usr/obj;fs:=/usr/obj I then created these symlinks: /usr/src => /net/usr.src /usr/obj => /net/usr.obj which has the desired effect of touching /net/usr.src when /usr/src is needed, and similarly for /usr/obj, so that amd will automount these dirs. I then build the kernel for fatso on balance using: cd /usr/src; make buildkernel KERNCONF=FATSO Then my problem occurs when I do (on fatso): cd /usr/src; make installkernel KERNCONF=FATSO because of the symlinks /usr/src => /net/usr.src => /.amd_mnt/... where /.amd_mnt/... is the real mount point for balance:/usr/src. Somewhere in the installkernel process there is a call to get the CWD which returns the real mount point (ie /.amd_mnt/...) which then seems to be appended to /usr/obj so it starts looking for files in /usr/obj/.amd_mnt/... which doesn't exist. I guess normally this would be /usr/obj/usr/src/..., but because my /usr/src is really pointing to /.amd_mnt/... it ends up looking for /usr/obj/.amd_mnt/... instead. What's the solution to this? I can add fs:=/usr/src and fs:=/usr/obj to my /etc/amd.map entries so that they become real mount points but then I would have to touch /net/usr.src to mount /usr/src which loses me the ability to just cd /usr/src and make. Please CC me on replies, I am not subscribed to questions. Thanks in advance, yun To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
