Entonces, estoy usando chroot para hacer chroot en Debian Bootstrap. Todo funcionó perfectamente en la cuenta raíz hasta que agregué un nuevo usuario y descubrí que no puedo actualizar ni acceder a la IP de xdisplay o localhost, lo cual es extraño, no sabía qué hacer, así que Estoy pidiendo ayuda. Aquí está el script chroot que estoy usando.
~ $ cat chroot.sh
sudo mount -t proc /proc chroot-ubuntu/proc
sudo mount --rbind /sys chroot-ubuntu/sys
sudo mount --rbind /dev chroot-ubuntu/dev
sudo mount /system/ chroot-ubuntu/system/
unset LD_PRELOAD
env -i HOME=/root \
PATH="/usr/local/sbin:/usr/local/bin:/bin:/usr/bin:/sbin:/usr/sbin:/usr/games:/usr/local/games:/opt/wine-5.3/bin/:/opt/wine-staging/bin/" \
TERM="xterm" \
BASH="/usr/bin/bash" \
SHELL="/usr/bin/bash" \
PREFIX="/usr" \
MDIR="/tmp" \
LD_LIBRARY_PATH="/lib:/usr/lib:/usr/lib/i386-linux-gnu/:/var/lib:/var/lib/dpkg/:/lib/i386-linux-gnu:/usr/local/lib:/opt/wine-stable/lib:/opt/wine-stable/lib/wine:/opt/wine-5.3/lib:/lib:/lib/wine:/lib/wine/fakedlls:/opt/wine-staging/lib" \
chroot chroot-ubuntu/ /bin/bash
Ejecuto chroot.sh usando sudo para que siempre esté en la cuenta raíz. Vamos a agregar un nuevo usuario. Obtengo este resultado extraño.
root@localhost:~# adduser g
Adding user `g' ...
Adding new group `g' (1000) ...
Adding new user `g' (1000) with group `g' ...
Creating home directory `/home/g' ...
Copying files from `/etc/skel' ...
passwd: user 'g' does not exist
Permission denied
Try again? [y/N]
y si intento agregar una contraseña al nuevo usuario, obtengo
root@localhost:~# passwd g
passwd: user 'g' does not exist
Así que tuve que agregar un usuario manualmente, lo cual hice (no recuerdo cómo).
aquí está la salida de ifconfig en root y usuario
root@localhost:~# ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
observe que inet 127.0.0.1 no está allí cuando realiza ifcnfig en el usuario
spiral@localhost:~$ /sbin/ifconfig
warning: no inet socket available: No such file or directory`
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet6 ::1 prefixlen 128 scopeid 0x10<host>
en cambio hay warning: no inet socket available: No such file or directoryerror
