SOLVED Script problem in "/usr/local/sbin/reboot"

Crontab for a nightly reboot fails due to dirty bit

I tried a crontab -e code below - to do a nightly reboot

0 4 * * *  /usr/local/sbin/reboot

Problem is that fsck is called by the /etc/init.d/reboot script; such that the fsck check fails due to the dirty bit being set and fsck fails to fix it, but opens a Maintenance shell that requires human input to fix the problem (at 4am?) and then to exit with ctrl+D to allow the restart to continue.

I found that when I burnt raspbian8 jessie image to sdb, the dirty bit was set in the burned image. which prevented a crontab reboot. That asside this also happens with a dirty bit on Rpi /dev/mmcblk0p1

Ayone know how I stop the Maintenance shell opening?

The sixth column of /etc/fstab specifies whether fsck should run against the volume at boot.

Find the line in fstab and set the sixth column to 0.

"man fstab" for more info.

Not sure why it would be different, but we regularly do this without problems with an entry in /etc/crontab:

30 1 * * * root /usr/local/sbin/reboot >/dev/null 2>&1
