Is there a reason for no  copy2fs  boot code?
If I get it right, when booting off of CD, there is no way to eject the CD after boot, unless it was remastered with added  /etc/sysconfig/tcedir/copy2fs.flg .
I'm currently thinking about how to add the  copy2fs  boot code to  tc-config  and   tce-setup  but please stop me if you know this would break things, as I'm not familiar with every method Core offers for loading extension (builtin/*.gz, *.tcz, PXE, etc.).
