Hi, I've been trying out your Debian Interix port but I would like
to preserve the Interix environment at the same time. I saw some
mentions of a chroot bootstrap mode in the setup scripts and was
wondering if you wouldn't mind walking me through the procedure to
set up a chrooted Debian environment.
first of all sorry for the late reply. I was busy with other things
the last days.
Thanks for your interest in debian-interix. I'll send a copy of this
mail to the mailing list for archiving.
To your question: A complete chroot install (without modifying
anything outside the chroot) is not supported. I created the chroot
options for creating another debian-interix installation on top of an
existing one for automated package building.
Such a build chroot only works on Vista and above, because the
chroot() syscall is unfortunately broken on older versions,
see http://debian-interix.net/bugs/kernel/#chroot for details.
Another limitation even on Vista and above exists: there is no /proc
file system within a chroot which makes some programs fail. And you
can't connect to network shares from within the chroot either, because
/dev/fs and /net work only in the main system.
I have scripts to set up such a build chroot, but these scripts
require several files/programs of debian-interix in the main system to
run correctly (debootstrap, apt-get, etc.).
If you don't want to modify anything outside the chroot, you might
look at the gentoo prefix. If you just need a backup to return to
after testing, you can copy all files of C:\WINDOWS\SUA to a backup
dir, and then test install debian-interix. If you need to revert, you
can rename the copy. debian-interix doesn't install anything outside
If you want to do a normal debian-interix install and have
difficulties with it or if you have a running debian-interix install
and want to set up a chroot within it, I'll help you with it.
Hope this helps
