Próbuję zainstalować Debian jessie w chroot w systemie wbudowanym (QNAP NAS z jądrem 2.6.33.2). Udało mi się uruchomić, debootstrap
aby zainstalować system podstawowy, a chroot działa poprawnie, ponieważ jestem w stanie zaktualizować pakiety za pomocą apt-get
.
Problem pojawia się podczas dodawania nowego użytkownika: su
zawsze drukuje su: Błąd krytyczny - natychmiastowe przerwanie . Oto wydruk:
CHROOT:/# whoami

CHROOT:/# id
uid=0(root) gid=0(root) groups=0(root),100(users)

i za każdym razem, gdy próbuję, su
ten błąd pojawia się na dmesg

Czy jest to związane ze starą wersją jądra? Czy mogę zrobić wszystko, aby obejść ten problem, ponieważ oczywiście nie mogę zaktualizować jądra?
Nawiasem mówiąc, mam BARDZO stary chroot Lenny, który został stworzony w ten sposób i w tym samym systemie działa poprawnie.
strace su root
