Has anyone had this problem and solved it? Would it for exampel work if I started cupds at the end of the installation ($ROOTCMD /etc/init.d/cupsys start) Any other suggestions? For my printer server I made a tar of /etc/cups that get's reinstalled. All others nodes just listen what the cups server announces. No need to do anything for them. If you had to add a local printer, I would setup it like: install the /etc/cups/ppd/my-printer.ppd And the section printer my-printer ... /printer from /etc/cups/printers.conf. During install cat my-printer.conf /etc/cups/printers.conf I.e. no need to use lpadmin and have cupsd running ;) Achim /Per -- To me vi is Zen. To use vi is to practice zen. Every command is a koan.

(I don't want to create a default file - I don't want mistakes to happen when somebody randomly net-boots some machine!) Currently fai-chboot does not has options for adding initrd information. But you can create a template manually, and then use the copy option -c. See man fai-chboot for more details. -- regards Thomas

I found the same problem. What I've been doing is creating an init script to run on the first reboot of the machine, which then finishes the job when CUPS is running. The script then deletes itself when it's finished. Here's an example install script from FAI: #!/bin/sh # # We copy an init script to do the dirty work on reboot, so that we have CUPS # running properly, and so on. It's a dirty hack, but it works. fcopy /etc/rc2.d/S20installprinter And the script in question: #!/bin/sh /usr/sbin/lpadmin -E -plab -DHP Laser Printer -vparallel:/dev/lp0 -P/usr/share/ppd/hpijs/HP/HP-LaserJet_4V-hpijs.ppd /usr/bin/cupsenable lab /usr/sbin/lpadmin -d lab rm /etc/rc2.d/S20installprinter Same strategy works for other things which require a running system to pull off. -Lou
Logfiles
Yo! Another small issue: while the installation copies back the log files just fine, softupdates don't. FAI_LOGPROTO=ssh and LOGUSER=fai are set. I don't even find something in the log, fai.log ends like: +++ The softupdate took 26 seconds. Source hook: savelog.LAST.source ERRORS found in log files. See /var/log/fai/current/error.log. savelog.LAST.source OK. Calling task_savelog +++ (error.log is not useful either; there are some errors because my package list is not entirely up to date yet.) cheers -- vbi (this is fai-client 3.1.6 on current etch) -- Enter any 11-digit prime number to continue... pgp0XgQ6kWpxJ.pgp Description: PGP signature

Thanks, as you say, on less reboot. I try to use the same config for install and softupdate, but you solutions could easily be tweaked into running the script immediately on a softupdate: fcopy /etc/rc2.d/S20installprinter if [ $FAI_ACTION == softupdate ]; then /etc/rc2.d/S20installprinter fi To those who suggested fcopy/ftar: I try to avoid that approach for configuration files. The reason is maintainability. With fcopy most of the files need to be replaced when upgrading to a new debian version. However, using cfengine, debconf and configuration utilies like lpadmin, most of the local changes survive the upgrade. And I do of course have the same possibility to take advantage of the class hieracy in shell scripts (ifclass CLASS) and cfengine scripts (CLASS::). Cups is an excellent example: The upgrade from sarge to etch (cups 1.1.23 to 1.2.7) is a major cups upgrade, and the config files are probably not portable, but the lpadmin approach is. /Per
