/source helyett /-rel, hogy ne kelljen kipreparalnom egy jailt.
~# chroot / /bin/bash << CHROOTED

> CHROOTED
bin dev initrd lib mnt sbin tmp vmlinuz
boot etc initrd.img lost+found proc srv usr vmlinuz.old

~# chroot /
/# ls
./ cdrom@ initrd/ lost+found/ root/ tmp/ vmlinuz.old@
../ dev/ initrd.img@ media/ sbin/ usr/
bin/ etc/ initrd.img.old@ mnt/ srv/ var/

Lathatoan az "here-document" a gond, nem a chroot.
File-bol veve a parancsokat jol mukodik.
Igy aztan ezt javaslom:
~# echo 'ls
> echo $?
> ls asdfasdf
> echo $?
> ' | chroot / /bin/bash
bin dev initrd lib mnt sbin tmp vmlinuz
boot etc initrd.img lost+found proc srv usr vmlinuz.old
cdrom home initrd.img.old media root sys var
0
ls: asdfasdf: No such file or directory
2
