Dear maintainer,
Attached please find the patch file to address this bug.
In /usr/share/debootstrap/scripts/debian-common,
The function first_stage_install () {
...
if doing_variant fakechroot || [ "$CONTAINER" = "docker" ]; then
setup_proc_symlink
fi
which will make the chroot's /proc in docker instance link the host's /proc.
Hence in the function "setup_proc" in /usr/share/debootstrap/functions,
this line:
umount "$TARGET/proc" 2>/dev/null || true
will unmount the docker instance's /proc, and it causes this issue.
I believe you definitely have a better solution for this, but the patch
for debootstrap 1.0.120 works for me.
My 2 cents.
Steven
