For those who have been following here or whose web search on this problem hits this thread in the mail archive:
For my LTSP-PNP installation on *buntu 13.10 (but not older *buntu's), clients fail to boot. After the splash screen, a text screen reads: Error: socket failed: connection refused. Exiting. Then it dumps me to a working busybox (initramfs) shell prompt. The last messages on the screen: Trying to load: pxelinux.cfg/default ok mount: mounting /dev/nbd0 on /root failed: Invalid argument /scripts/init-bottom/ltsp: line 27: panic: not found chroot: can’t execute ‘/usr/bin/test’: No such file or directory mount: mounting /root on /rofs failed: Invalid argument mount: mounting /rofs on /root/rofs failed: Invalid argument mount: mounting /dev /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target filesystem doesn’t have requested /sbin/init-ltsp. No init found. Try passing init= bootarg. -------------------------------------- Alkis G found the problem and solution in a whirlwind remote control session. As indicated at https://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2509/client/Debian/share/initramfs-tools/scripts/init-premount/udhcp <https://bazaar.launchpad.net/%7Eltsp-upstream/ltsp/ltsp-trunk/revision/2509/client/Debian/share/initramfs-tools/scripts/init-premount/udhcp>, it seems that there is a new capitalization rule, or an old rule is now being enforced strictly. The problem is fixed for Ubuntu 14.04 and for 12.04 in the Greek schools' ppa. The workaround for 13.10 on Ubuntu is to edit /usr/share/initramfs-tools/scripts/init-premount/udhcp as indicated in the 4 instances. Then get the revised initrd image into play for clients. I'm not sure what the shortest/best method is for doing that and I tripped on it for a while when trying to recreate the fix on another test server. This should do it: sudo update-initramfs -u sudo ltsp-image-update -c / But I'm thinking that Alkis probably just did "sudo update-initramfs -u" and then simply copied the current /boot/initrd.img-3.x.x-xx-generic image to /var/lib/tftpboot/ltsp/i386/. Care to confirm/correct/comment on any of this, Alkis? ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
