NAME

       ltsp initrd - create the ltsp.img initrd add-on

SYNOPSIS

       ltsp [ltsp-options] initrd

DESCRIPTION

       Create  a  secondary initrd in /srv/tftp/ltsp/ltsp.img, that contains the LTSP client code
       from  /usr/share/ltsp/{client,common}  and  everything  under  /etc/ltsp,  including   the
       ltsp.conf  settings  file.  Additionally  it  contains  the  server users and groups lists
       (passwd/group) and public SSH keys.  LTSP clients receive this initrd in addition to their
       usual one.

       This  means  that  whenever  you  add new users or edit ltsp.conf(5), you need to run ltsp
       initrd to update ltsp.img, and reboot the clients.

       It also means that you can very easily put template xorg.conf or sshfs or other  files  in
       /etc/ltsp, and have them on the clients in seconds, without having to run ltsp image.

OPTIONS

       See the ltsp(8) man page for ltsp-options.

EXAMPLES

       Most live CDs do not contain sshfs, so by default you can only use NFS home with them. But
       sshfs is a small binary without many dependencies, so you may usually provide  it  to  the
       clients if you include it to ltsp.img:

              mkdir -p /etc/ltsp/bin
              cp /usr/bin/sshfs /etc/ltsp/bin/sshfs-$(uname -m)
              ltsp initrd

       You  can  even provide multiple sshfs versions for different architectures.  LTSP contains
       code to automatically use those sshfs binaries if it can't find the /usr/bin/sshfs one.
