Re: [Ltsp-discuss] ltsp@debian: Upgrade of chroot to squeeze gives nfsmount: need a path error
I just did a fresh ltsp-build-client --dist squeeze --mirror http://ftp.de.debian.org/debian/ and strangely enough now this setup tries to boot from the last device it finds (eth2) which is not the one it should use (eth0). At least it uses ipconfig now to get the dhcpd information. ipconfig (as used in initramfs-tools in squeeze) should ask on all available interfaces, and takes the first that gives a DHCP response... do you have your thin client on multiple networks with DHCP on every network? Yes, that is how we do it here... we basically use LTSP as the base of our computing cluster (by uninstalling ltsp-client and installing ltsp-client-core) ... dpkg -P ltsp-client apt-get autoremove apt-get install ltsp-client-core ... So we do not have to maintain a whole setup of Diskless Server setup scripts... How can we force it to use the first device? (still under the nfsmount: need a path error-description since it shows the same error ;-) ). you can do a couple things: 1) set ipappend 2 in /var/lib/tftpboot/i386/ltsp/pxelinux.cfg/default which passes the mac address of the network card it's booting and initramfs-tools will use the interface that matches that mac address. This is what sounds more clever... I did not know about this yet, but was wondering why the heck parameter BOOTIF was empty... 2) in /opt/ltsp/i386/etc/initramfs-tools/initramfs-tools.conf hard-code DEVICE=eth0. then rebuild your initramfs: ltsp-chroot update-initramfs -u and update the tftp dir(s) ltsp-update-kernels. hard-coding eth0 was the default on lenny, but typically didn't work well with multi-NIC setups if you wanted to boot from anything other than eth0. Which is what I found by myself - going to take that away again... live well, vagrant Thanks!!

Re: [Ltsp-discuss] ltsp@debian: Upgrade of chroot to squeeze gives nfsmount: need a path error
I found the regression: udhcpc is called in init-premount to get the DHCP configuration. The udhcpd used in the busybox does not ask the DHCP server for the rootpath option. Adjusting the udhcpc call in /usr/share/initramfs-tools/scripts/init-premount/udhcp with -O rootpath fixes my problem. udhcpc isn't part of the default LTSP install on Debian. there are hooks to use it if present. so apparently you've got a customized install.

Re: [Ltsp-discuss] ltsp@debian: Upgrade of chroot to squeeze gives nfsmount: need a path error
Hi, not like that: We install only the debian package ltsp-client-core and use that to have a base for diskless booting. In the chroot we install packages like apache or mysql and then mount additional filesystems from the NFS server like /var/lib/mysql, /root and /home. So instead of inventing the wheel of Diskless booting we used ltsp... But of course - with a centralised Storage you could also boot ltsp Servers from the net. @all: Has anybody else upgraded a chroot yet from lenny to squeeze?
