私は、組み込みシステム(カーネル2.6.33.2のQNAP NAS)のchrootにDebian jessieをインストールしようとしています。私はうまく走った debootstrap
基本システムをインストールする方法とchrootは正しく動作します apt-get
。
新しいユーザーを追加すると問題が発生します。 su
常に印刷 su:重大なエラー - 即時中止 。これがプリントアウトです。
CHROOT:/# whoami
root
CHROOT:/# id
uid=0(root) gid=0(root) groups=0(root),100(users)
CHROOT:/# su root
su: Critical error - immediate abort
CHROOT:/# adduser newuser

Changing the user information for newuser
Enter the new value, or press ENTER for the default
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n] Y
CHROOT:/# su newuser
su: Critical error - immediate abort
そして私が試すたびに su
このエラーは dmesg
:
CHROOT:/# dmesg
CHROOT:/# su root
su: Critical error - immediate abort
CHROOT:/# dmesg

それは古いカーネルバージョンに関連するものですか?明らかにカーネルをアップグレードすることはできないので、この問題を回避するために何かをすることができますか?
ちなみに、私はこの方法で作成された非常に古いlenny chrootを持っていますが、同じシステムでそれは正しく動作します。
strace su root
