[syslinux] use of APPEND in default

[Chris Suttle]

Having fought my PXE config and eventually getting it to work (had to
comment out the group { } statments ?

I now come across another issue I cannot resolve and would appreciate some
help.

in my /tftpboot/pxelinux.cfg/default file I have cause to use the APPEND
statement to pass options
to the kernel being used.

Unfortunately this line has now become longer than 255 characters and
appears to be failing because of this.

Any suggestions as to how best overcome this, the line length is borne out
of a lot of historical data.
Can or how could I substitute variable declarations in this file.
