nfsroot.conf - nfsroot configuration for FAI




The nfsroot is a file system on the install server. It is used during installation by the install clients. nfsroot.conf defines the essential options for the install server, which are mostly used inside the nfsroot. Use bash(1) syntax for defining variables.


FAI_DEBOOTSTRAP Two parameters for debootstrap(8), space separated. Debootstrap is called as the first part of fai-make-nfsroot unless -B is used. This variable defines SUITE and MIRROR for debootstrap. Example: FAI_DEBOOTSTRAP="wheezy" NFSROOT_ETC_HOSTS This multiline variable is added to /etc/hosts inside the nfsroot. You can use this when DNS is not available on the clients. Example: NFSROOT_ETC_HOSTS=" faiserver" FAI_ROOTPW The encrypted root password on all install clients during the installation process. Used when log in via ssh. This is not the password for the new installed system. Example: FAI_ROOTPW='$1$kBnWcO.E$djxB128U7dMkrltJHPf6d1' # pw is fai Use mkpasswd, htpasswd or md5pass for generating the password hash. echo "yoursecrectpassword" | mkpasswd -Hmd5 -s NFSROOT Directory on the install server where the nfsroot is created. TFTPROOT Directory on the install server for the tftp data, used by PXE network boot. FAI_CONFIGDIR Location of the configuration space on the install server. Used by fai-cd(8), fai- mirror(1) and fai-setup(8). SSH_IDENTITY Location of a ssh public key file. This user can log into the install clients in as root without a password. Only useful with FAI_FLAGS="sshd". Example: SSH_IDENTITY=/home/admin/.ssh/ NFSROOT_HOOKS Directory of hooks to be sourced at the end of fai-make-nfsroot, i.e. they have to be shell scripts. FAI_DEBOOTSTRAP_OPTS Options that will be passed to debootstrap(8). Used for excluding packages and for specifying a different architecture.


Normally, the nfsroot is mounted by the install kernel via NFS. It's also used on the FAI CD. FAI clients can also receive the nfsroot via http. There you have to create a com‐ pressed squashfs image of the nfsroot with fai-cd(8).
