My idea about the write command is that it could serve as a
replacement for kernel parameters whenever an OS needs to be
chainloaded. That way also non-directly supported OSes like Windows or DOS or any new not yet supported ones could be customized.
The command found for fdubcd.img.gz is:
write --offset=15 /bin/setargs.bat ubcdcmd=keydisk\r\n
It simply replaces the given file for the given string at the given offset. The file itself contains sufficient spaces at the given position in order to hold for the parameter passed via write. As already said there are no additional security/safety considerations necessary as long as the file resides inside a RAM disk.
