मैं एक एम्बेडेड सिस्टम पर चेरोट के अंदर डेबियन जेसी को स्थापित करने का प्रयास कर रहा हूं (QNAP NAS कर्नेल 2.6.33.2 के साथ)। मैं debootstrapबेस सिस्टम को स्थापित करने के लिए सफलतापूर्वक चलाता हूं और चेरोट सही तरीके से काम करता है क्योंकि मैं उपयोग करने वाले पैकेज को अपडेट करने में सक्षम हूं apt-get।
समस्या तब होती है जब एक नया उपयोगकर्ता जोड़ते हैं: suहमेशा su प्रिंट करता है : महत्वपूर्ण त्रुटि - तत्काल गर्भपात । यहाँ एक प्रिंटआउट है:
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
Adding user `newuser' ...
Adding new group `newuser' (1000) ...
Adding new user `newuser' (1000) with group `newuser' ...
Creating home directory `/home/newuser' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
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
और हर बार जब मैं कोशिश करता हूं तो suयह त्रुटि दिखाई देती है dmesg:
CHROOT:/# dmesg
CHROOT:/# su root
su: Critical error - immediate abort
CHROOT:/# dmesg

क्या यह पुराने कर्नेल संस्करण से संबंधित है? क्या मैं इस मुद्दे को दरकिनार करने के लिए कुछ भी कर सकता हूं, क्योंकि मैं स्पष्ट रूप से कर्नेल को अपग्रेड नहीं कर सकता हूं?
वैसे, मेरे पास एक बहुत पुराना लाल मिर्च है जो इस तरह से बनाया गया था और उसी प्रणाली में यह सही ढंग से काम करता है।
