Using debian in beaglebone black. The board is connected online with a static ip for remote ssh. After few days I couldn't able to ssh my board. While debugging the board received following error log.

Failed to start Create Volatile Files and Directories. 

Failed services: Volatile file creation, ssh-server, networking service etc. Failed to start.

What may be went wrong ? Have anyone faced similar issue.

  • That's not your log. That's what's printed to your console. Look at, and show people, your actual journal. – JdeBP Oct 4 '18 at 7:02

Make sure that the root filesystem is rw

I had this problem when I was trying to create a debootstrap image that works on QEMU.

After some Googling on random forums, I found that the solution is to make the root filesystem read-write, instead of the default read-only that the Linux kernel mounts it as.

The most correct way to do that in Debian is to add to your fstab:

/dev/sda / ext4 errors=remount-ro,acl 0 1

which remounts the root with the default rw parameter, although I haven't tested it yet.

The root problem with debootstrap is that the fstab is just a dummy as explained at: https://askubuntu.com/questions/557556/why-is-my-etc-fstab-file-unconfigured/1080541#1080541

An alternative that might work would be to pass the rw kernel boot parameter, but I haven't tested it in Debian, only Buildroot.

The final working debootstrap setup I achieved is described at: Creating bootable Debian image with debootstrap
