Description

In wrlinux 5, simple file permissions are not being retained when copying the file created on a yaffs partition

touch file1
chmod 777 file1
cp -a file1 file2
ls -la file*
-rwxrwxrwx 1 root root 0 Aug 11 08:28 file1
-rwx------ 1 root root 0 Aug 11 08:28 file2

Workaround

Currently the YAFFS2 fs seems support xarrt but it can't works in order with other kernel mechanism and common user space tools as other file systems. So please just remove this feature as below:
