How to edit the linuxrd: gunzip /tftpboot/lts/2.4.26-ltsp-2/initrd-2.4.26-ltsp-2.gz
mount -o loop /tftpboot/lts/2.4.26-ltsp-2/initrd-2.4.26-ltsp-2 /mnt/iso (you have to create a directory where to mount the image, I call ist /mnt/iso) then you can cd to /mnt/iso and edit everthing you want, especially the NFS mount section, as described in: http://wiki.ltsp.org/twiki/bin/view/Ltsp/Troubleshooting-mount-problems after your editing: umount /mnt/iso gzip /tftpboot/lts/2.4.26-ltsp-2/initrd-2.4.26-ltsp-2 Thats it. But keep a Backup of your initrd before you edit something :-) I have done this, but I have another Problem now: on the machines I had the problem with Pivot root Mounting, I face now a very bad performance on the Xserver. For me it seems, that there are packets lost. The mouse and the keyboard have a dely on input, and the screen output is also very, very delayed... So in Fact I canīt work on this clients... Is there a way to manage Packet size between Xserver and clients? thanks Robert Am Freitag, 25. Februar 2005 10:47 schrieb Marvin T.
