copy2fs boot code
« on: October 18, 2016, 05:16:26 AM »
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.).

Yeah, too easy. Doesn't work for  base .
I might wait for comments before I dig further.

This works for me:
Code: [Select]
$ sudo umount /mnt/sr0
$ eject

Really? Shouldn't it refuse to un-mount while there are extensions mounted from sr0 (resource or device busy) ?

Oh, yes!
There is  /cde/copy2fs.lst , containing every extension stored in  /cde/optional . Big oversight. :p
This probably reduces my efforts by some degree as CDs are not affected.
I'd still find a  copy2fs  boot code useful but I'm realizing now that it's not really required. Maybe I'll come back to this if I can get it done without complicating things.
