Good Day Jürgen,

fai-make-nfsroot will create the FAI nfsroot directory as
pointed by $NFSROOT, defined in nfsroot.conf.  If this variable
is not set, then the default is /srv/fai/nfsroot, which would be
hosted inside your root partition /dev/sda1.  Since it has to be
a fully operational system, the whole NFS root wouldn't have
been able to fit in the 97M left, although it represents 31% of
free space.

You can add a partition to host your /srv perhaps, if you have
enough room left on your drive.  Or you can change the
configuration to point the location of your NFS root somewhere
else.  If you choose this second course of action, modify also
the $FAI_CONFIGDIR, which points to /srv/fai/config by default.

You may wish to have a look at nfsroot.conf(5) and fai.conf(5)
manual pages, for more details on available variables:
