Hi, I have an imx6dl based custom board. I compiled OpenWRT Chaos Calmer for this and generated an image out of u-boot.img, zImage and dtb file in one partition and rootfs in second partition. First partition is vfat and second(rootfs) is ext4. The board can boot from SD card and internal eMMC flash. I tried on both of them. Steps to reproduce: 1. Boot the image. 2. Change passwd to a non-empty string 3. Observe there is no passwd+ file in the /etc/ directory 4. Do a hard reboot (Soft reboot doesn't reproduce this) 5. Observe that passwd+ file exists in /etc/ directory. (Happens more than 80% of the time) 6. Now unless we remove this file, passwd cannot be changed. root@OpenWRT:~# passwd Changing password for root New password: Bad password: too short Retype password: passwd: can't create '/etc/passwd+': File exists passwd: can't update password file /etc/passwd This cannot be a busybox issue. The problem comes because passwd+ file recovers after it got deleted upon reboot!! I will upload the required logs/docs/info if specified.
