A succesfull 'append line' in pxelinux.cfg is
append initrd=initrd.gz ramdisk_size=9310 root=/dev/rd/0 rw
preseed/url=http://bahrain/gs/seeds/bd.text
languagechooser/language-name=English
countrychooser/shortlist=NL console-keymaps-at/keymap=us
netcfg/get_hostname=s netcfg/get_domain=s --
Note that there are nine(9) equal signs(=)
All nine are shown in /proc/cmdline, `set` showns only seven,
the "dropped ones" are ramdisk_size= and root=
those are the later in the alphabeth.
This report of a succes does _not_ mean that the problem is gone,
it is only to tell about the workaround.
Please extend the limit in the environment parameters.
