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.

Variables that are unused since 3.x versions of FAI:
| name | type | example value | created by | used by | comments |
|---|---|---|---|---|---|
| FAI_REMOTECP | scp | fai.conf | fai-savelog | replaced by FAI_LOGPROTO | |
| FAI_REMOTESH | ssh | fai.conf | fai-savelog, task_chboot() | replaced by FAI_LOGPROTO | |
| FAI_LOCATION | faiserver:/srv/fai/config | make-fai-nfsroot | get_bootp_info() get_fai_dir() get_fai_cvs() | replaced by FAI_CONFIG_SRC | |
| FAI_LOGPROTO | ftp | fai.conf | fai-setup, save_log_remote() | replaces FAI_REMOTECP and FAI_REMOTESH, may be removed from fai.conf, should be defined in class/*.var, but fai-setup needs this too, maybe add option to fai-setup that determines if ssh/rsh should be set up | |
| diskvar | int | $LOGDIR/disk_var.sh | removed, replace with "$LOGDIR/diskvar" | ||
| lpipe | int | /tmp/fai/logfifo | variable removed, try to remove the ugly hack using it | ||
| FAI_BOOT | dhcp bootp | make-fai-nfsroot | removed | ||
| DNSDOMAIN | workgroup.de | task_setup() | removed | ||
| installserver | kueppers | fai.conf | only for building FAI_LOCATION | removed | |

| fstab | int | fstab | was used for solaris, fstab -> vfstab | removed | |
| VIDEODRIVER | CS | mga | 20-hwdetect.source | scripts/DEMO/10-misc | removed with Xorg |
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' {} \;
