I have in the past used debootstrap
to bootstrap both Debian and Ubuntu systems. But this time, trying to bootstrap a Ubuntu system from a Debian 6 rescue system (Note: I have no choice about the rescue system, so please don't suggest using Ubuntu or such, it wouldn't be available to me).
Consider the following folder structure /target
which I want to use to bootstrap the system:
/dev/md0 on /target type ext4 (rw,relatime,data=ordered)
/dev/md1 on /target/home type ext4 (rw,relatime,data=ordered)
/dev/md2 on /target/var type ext4 (rw,relatime,data=ordered)
Now I am running the following debootstrap
command:
# LANG=en_US.UTF-8 debootstrap --exclude=dhcp3-common,dhcp3-client,laptop-detect,tasksel,tasksel-data --include=bash-completion,sudo,lshw,tmux,mercurial,etckeeper,unzip,mc,htop,pciutils,usbutils,openssh-server,localepurge,unattended-upgrades --print-debs --variant=minbase --arch=amd64 precise /target

I: Deleting target directory
rm: cannot remove `/target/var': Device or resource busy
rm: cannot remove `/target/home': Device or resource busy
I am running this as root
, but the last three lines throw me off. If I try the same but without /target/var
and /target/home
, the last lines change to:
I: Deleting target directory
rm: cannot remove `/target': Device or resource busy
I am using:
# debootstrap --version
debootstrap 1.0.42ubuntu0.1
from here and I installed it via dpkg -i debootstrap_1.0.42ubuntu0.1_all.deb
which claimed to be successful. I have also attempted to install the variant buildd
instead of the minbase
one. Same result.
What is going on here? Why does debootstrap
attempt to remove the target folder?
Note: I also checked the man
page, but cannot find an option to prevent this attempted removal.
Also note: installing the keyring for the Ubuntu archive doesn't change a thing. I used wget -O /usr/share/keyrings/ubuntu-archive-keyring.gpg http://archive.ubuntu.com/ubuntu/project/ubuntu-archive-keyring.gpg
for it.
