snapshot fails to boot (a little help needed) [solved]

[Member manyroads]

I am trying to build a snapshot of antiX19-alpha2 (customized a bit by me).

I have tried now three times and every snapshot returns the following error on initial boot:

Fatal Error
Neither aufs nor overlayfs is available

I am booting in the same VBox setup where the initial earlier snapshot is running (from which this snapshot is derived). Is there a reasonably easy fix, for a slow learner, available.

did you change kernels?

No I did not change the kernel.

This is a second generation build
1. alpha1 to alpha 2 (built snapshot 1) “works”
2. snapshot 1 some Desktop edits (build snapshot 2) “does not work”

Note: what kernel(s?) should work… I can reinstall/install them perhaps?!?!

If you did not change the kernel then the “overlay” module should be available so the problem is likely in the snapshot procedure, not in the kernel.

There should be a couple of new tools in antiX-19 that will help us diagnose this. Perhaps you could try these two commands

sudo isomount $SNAP_SHOT_FILE
unpack-initrd -f /mnt/iso/iso1/antiX/initrd.gz

The first command should mount the snapshot iso at /mnt/iso/iso1. The 2nd command will create an “initrd” directory and unpack that snapshot initrd.gz file into it.

We can then look for all of the kernel modules in the initrd. There should be 70 or 80 of them. You can list them all with:
find initrd/lib/modules -name "*.ko" -printf "%f\n" | sort

You can count them with:
find initrd/lib/modules -name "*.ko" -printf "%f\n" | wc

And you an look for the overlay module with:

find initrd/lib/modules -name "*.ko" -printf "%f\n" | grep overlay

As a double-check, you can make sure you kernel compiles overlay as a module:
cat /boot/config-$(uname -r) | grep -i overlay
Here I get the output:
CONFIG_OVERLAY_FS=m
which means overlay is compiled as a module so that module needs to be in the live initrd for the live initrd to boot.

The first of two commands produced:

$ sudo isomount /media/sf_mark/snapshot/test-antiX-prototype.iso
isomount: Mounted /media/sf_mark/snapshot/test-antiX-prototype.iso at /mnt/iso/iso1
isomount: Mounted /mnt/iso/iso1/antiX/linuxfs at /mnt/iso/sq1

isomount mount-points
File                                              Type      Size  Mounted at   
/media/sf_mark/snapshot/test-antiX-prototype.iso  iso9660   1.1G  /mnt/iso/iso1
/mnt/iso/iso1/antiX/linuxfs                       squashfs  1.1G  /mnt/iso/sq1 

The second was less useful:

$ unpack-initrd -f /mnt/iso/iso1/antiX/initrd.gz
bash: unpack-initrd: command not found

Seems like something has gone “walk-about.”

Oops. I had requested that it be put on the PATH as part of the chroot rescue system but I didn’t check to make sure it was there. You can find it at: /usr/local/lib/cli-shell-utils/bin/unpack-initrd. You can run it directly from there or first copy it to /usr/local/bin:
sudo cp /usr/local/lib/cli-shell-utils/bin/unpack-initrd /usr/local/bin

I tried reinstalling aufs and overlayfs… my error on created snapshot(s) continues. Here’s the screenshot. Any ideas?

Do you have the latest versions of iso-snapshot-antix (0.3.5) and iso-template-antix (18.4) from the repos?

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.

I’m downloading 7 installing the repo versions now. I’ll report back what happens (either way).

Edit:
I managed to create a functional snapshot!

I added ‘solved’ to the original post.

Thank you. I tried but was unable to break the ‘code’.
