local variable 'bootfile_size' referenced before assignment

[Sector7CSD]

Hello,

when I try to boot RHEL 8.4 I encounter the following:

    15:38:39 PXE[pxed] CRITICAL: local variable 'bootfile_size' referenced before assignment
    Traceback (most recent call last):
      File "/home/cklein/Development/3rdParty/pybootd/pybootd/pxed.py", line 431, in start
        self.handle(sock, addr, data)
      File "/home/cklein/Development/3rdParty/pybootd/pybootd/pxed.py", line 843, in handle
        extra_buf = self.build_pxe_options(options, server, buf)
      File "/home/cklein/Development/3rdParty/pybootd/pybootd/pxed.py", line 498, in build_pxe_options
        if bootfile_size:
    UnboundLocalError: local variable 'bootfile_size' referenced before assignment

When I insert in the file pxed.py in the function build_pxe_options a line which sets the bootfile_size to 0 then it works:

    def build_pxe_options(self, options, server, bootp_buf):
        try:
            client_params = options[55]
        except IndexError:
            client_params = b''
        buf = b''
        bootfile_size = 0
        try:
            if 97 in client_params:
                uuid = options[97]
                buf += spack('!BB%ds' % len(uuid),
                             97, len(uuid), uuid)
        # etc
