How to set the grub to boot linux installed in directory an not in own partition
 

I did it long time with LFS but I don't remember how.

the "root" option of the kernel in grub except only the partition.

How do I set the "root" as a directory in a partition?


thanks
Nadav

can you please explain ?

what it is you want to do

is it set a partition as / during fedoras install?
if so that is automatic

I install arch to a folder: /home/projects/distro/arch/

How do I boot to it?

????????
fedora is under your name
now you say you installed Arch Linux to your home folder??????????

you do not install Arch ( nor any distro ) to your home folder

you repartition and install to a unformatted partition like
sda5 or sdb3 or something like that .

I want to be special! :P

If it possible systems like wuby why this not?

and I think that I remember correctly that I did this some years ago with LFS.
