Здравствуйте!

Расскажите, как я смог добиться такого эффекта?

# usermod -p "" user
usermod: cannot lock shadow password file
# strace -f usermod -p "" user
...
open("/etc/tcb/user/shadow.lock",
O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK|O_NOFOLLOW, 0600) = -1 EACCES
(Permission denied)
...
# echo hello > /etc/tcb/user/shadow.lock
# rm /etc/tcb/user/shadow.lock
rm: remove regular empty file `/etc/tcb/user/shadow.lock'? y
# usermod -p "" user
usermod: cannot rewrite shadow password file
# strace -f usermod -p "" user
...
open("/etc/tcb/user/shadow-", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1
EACCES (Permission denied)
...
# echo hello > /etc/tcb/user/shadow-
# rm /etc/tcb/user/shadow-
rm: remove regular file `/etc/tcb/user/shadow-'? y
# usermod -p "" user
#

На всякий случай: user был создан в процессе создания образа системы
средствами mkimage примерно так:

useradd user
usermod -G wheel user
usermod -p "" user

позавчера не смог авторизоваться в kde при включении компа

днём ранее обновлялся, больше ничего с системой ни делал

root'а пускает, остальных нет...

su - user
говорит UNKNOWN user

strace passwd user
говорит

Permission denied на shadow

find /etc/tcb/user -ls
   2217    4 drwx--s---   2 user      auth         4096 Июн  8 03:06 /etc/tcb/user
  67614    4 -rw-r-----   1 user      auth           77 Июн  8 03:06 /etc/tcb/user/shadow
  74693    0 -rw-------   1 user      auth            0 Июн  8 03:06 /etc/tcb/user/shadow.lock
  67617    0 -rw-------   1 user      auth            0 Июн  8 03:06 /etc/tcb/user/shadow-


Вошёл в систему только путём правки /etc/pam.d/system-auth
auth           requisite       pam_succeed_if.so uid = 500 quiet
account                requisite       pam_succeed_if.so uid = 500 quiet
password       requisite       pam_succeed_if.so uid = 500 quiet
session                requisite       pam_succeed_if.so uid = 500 quiet


В торой день таким образом авторизуюсь. В чём косяк не пойму..

система sisyphus x86_64
