The following Variables do exist in FAI (example values included):

Please do not edit that much, without contacting Mrfai. Currently it's my private list of variable and comments.

type: int = internal use only; CS used in config space (often defined by *.var)

Which variables are needed inside the nfsroot, so the install clients can use them? (maybe write them into fai-client.var or nfsroot.var). Then do not copy fai.conf into the nfsroot any more.

name type default value example value created by used by comments
--
FAI_CONFIG_SRC nfs://faiserver/srv/fai/config different sources get-config-dir fai-chboot -u, fai -s

FAI_CONFIGDIR /srv/fai/config nfsroot.conf *.postinst, fai-setup, fai-cd, fai-mirror, fai-make-nfsroot configs space on the server

MNTPOINT /media/mirror fai-make-nfsroot, fai-mirror, task_mirror() influences entries in sources.list, may become a fixed path
STOP_ON_ERROR 99999 class/*.var task_error() errors greater STOP_ON_ERROR will cause fai to stop the installation
SERVERINTERFACE eth0 nfsroot.conf fai-setup used to specify interface when building exportfs line, only needed when install server has multiple interfaces
FAI_DEBMIRROR $mirrorhost:/srv/debmirror fai.conf move to nfsroot.conf, but needed in $NFSROOT/../fai.conf
monserver kueppers task_confdir sendmon() name of host where faimond is running. default: monserver=$SERVER, but must be set before CS is available (e.g in fai.conf, kernel command line)
FAI_MONITOR_PORT 4711 task_confdir sendmon() port of the fai-monitor, must be set before CS is available (e.g in fai.conf inside the nfsroot or on the kernel command line)
duration int if set to 1 every task prints its execution time
--
target /target same as $FAI_ROOT

FAI_BACKUPDIR CS class/*.var fcopy directory used by fcopy for backup files
FAI_RAMDISKS CS $target/var/lib/dpkg class/*.var mkramdisk a space-separated list of a directories that gets a ramdisks, use NONE to disable this feature
--
FAI_ETC_DIR int /etc/fai /etc/fai fai -C fai-make-nfsroot, fai-mirror, fai-cd, fai via fai_init() -> /usr/lib/fai/subroutines (task_debconf, task_repository)
FAI_ROOT const /target bin/fai almost every script directory where the new system will be installed to, $target has the same value

Variables that are unused since 4.0 versions of FAI:

name type example value created by used by comments
FAI_NORAMDISK CS class/*.var mkramdisk if set to 1, no ramdisk will be created
USE_SETUP_STORAGE CS 1 class/*.var when set to 1, FAI will use the new partition tool setup-storage


Useful oneliners

find all files not under a ".svn" directory and replace the string '$diskvar' with '$LOGDIR/diskvar'

Test:

find -name '.svn' -prune -o -type f -exec perl -n -e 's/\$diskvar/\$LOGDIR\/diskvar/g && print' {} \;
find -name '.svn' -prune -o -type f -exec perl -p -e 's/\$diskvar/\$LOGDIR\/diskvar/g' {} \; | less

Really replace: ( same, but "i" added )

find -name '.svn' -prune -o -type f -exec perl -pi -e 's/\$diskvar/\$LOGDIR\/diskvar/g' {} \;
