Hi Dominik,

I think you may have misunderstood the point of this library. This
library is aimed at HelenOS, not to replace standard tools. It is for
the case when you have blank harddrive so that you can format it and
install HelenOS. It's not designed to fit all needs. If it is really
necessary (for inter-OS compatibility), you can use better tool
instead,
since you are going to be using a different OS anyway.
I tend to disagree, I'd like to be able to install HelenOS alongside
another operating system (or two) from within HelenOS, even on a
notebook computer with recovery partitions and such things. I think the
ultimate goal is for HelenOS to *be* the standard OS you use to run
programs on your computer ;)

I already have triple-boot setup on my laptop (Windows/Linux/HelenOS),
why should I have to purchase a separate hard-disk just to use the
installer on real hardware?

What I meant was that when you do this kind of setup, you partition the
drive from Linux anyway. I also have dual, triple or multiple boot
setups. When you get your hardware with preinstalled Windows, you have
to run Linux so that you can run ntfs-resize, for example. When you
don't plan on using Windows but only sensible OSs like Linux, then you
either partition the drive from Linux so that you can use LVM and other
advanced stuff, or you are just fine with LBA-only MBR from HelenOS.

OK, so if I add say working ext4fsresize (or ntfsresize) to HelenOS,
would the installation work on my computer without using Linux?
(It wasn't clear to me from your previous e-mail, since you mentioned
that it is for the case when you have a blank harddrive).

I don't see why not.
Cool, I'm looking forward to test it when I have more time :)

That's the spirit! :)


CHS has been obsolete since ATA5 or ATA6 (as I've
read) and even Windows have been using LBA since XP or Vista. But that's
not tested (I only know they refuse to work when there's wrong partition
type even though the FS is fine).
To be clear, my concern is more with preserving all the weird stuff some
vendors do with their recovery partitions and such (at least so I've
heard), not support for CHS.

OK. As Jiri Svoboda noticed, the current version does not preserve partition flags - simply because I didn't know about them. :) That means the those "hidden" recovery partitions would become visible.

Anyway, I hope I don't have to tell you always back up your MBR. libmbr still needs more testing.
