Hi, Okajima San,

       Please find the attachments which are the outputs of comannds
   execution in the unpreviliged container.

       I run the command :  useradd 1234, and got the warning: useradd:
   failure while writing changes to /etc/shadow

       and run:  chown _apt:root ./aaae (aaae is a txt file), and got
   warning: chown: changing ownership of './aaae': Operation not permitted



       But the kernel log still seems the same.

   I cannot see any error in your "strace touch newfile in unpreviliged
   containers.txt" and "strace touch newfile in parent server.txt".
   Please define a command to reproduce the error.
