gnu/linux and dragonflybsd on one drive

[Hleb Valoshka]

Hi everybody.

Will I have issues installing DFly on the same drive where Linux is
installed? I've got 240GB drive partitioned as hda1 - small linux
/boot, hda2 - linux LVM (120 GB), the rest is free. I want to install
DFly into spare space. I want to continue to use GRUB2 as main loader,
it is installed into MBR.

So the questions:
 1) will DFly installer overwrite MBR?
 2) is chainloading from grub is enough to load?
 3) what other issues I may have during/after installation.
