Description Philip Lawatsch 2005-03-24 01:34:40 UTC

I'd like the initrd to mount /dev/my_real_root and then use a directory inside this filesystem when chrooting. Currently you can only chroot to the root of the fs.
I know this might not be useful for the average user but it would be helpful if for instance one bootstraps a new gentoo system inside his old fs (/root/next_try/ for instance) and would try to boot it before replacing the old system with the new one.

Reproducible: Always
Steps to Reproduce:
1. Try to make genkernel's initrd cd to a path inside the real_root fs
2.
3.

Actual Results:  
doesnt do it

Expected Results:  
after mounting the fs cd to a speciefied directory and continue from there on

would a subdir=/foo type command work for you?

Comment 2 Philip Lawatsch 2005-06-21 23:30:33 UTC

Sure, everything is fine. I just need this to test a new gentoo root which I
compiled somewhere inside my filesystem. So if subdir=/foo chroots to
$mount_point_of_real_root/foo its fine with me.
