amd64 build failing on mount and unmount

[azaam1990]

When running the build for a couple of hours it is failing with an error on mount and unmount as shown in the log output below:

DEBUG:onlrfs:Executing:sudo mount -t proc proc stretch/rootfs-amd64.d/proc

I asked chatGPT could this be the solution? let me know:

The error you're seeing:

mount: mount point stretch/rootfs-amd64.d/proc does not exist
ERROR:onlrfs:Exception 'Could not mount proc in rfs.'

means the build system expected a directory proc inside your rootfs path but it wasn’t created beforehand.

---

✅ Quick Fix

Manually create the missing proc and dev mount points in the rootfs directory before retrying:

mkdir -p stretch/rootfs-amd64.d/proc
mkdir -p stretch/rootfs-amd64.d/dev

Then rerun the build:

make docker

---

🧠 Why It Happens

This happens if the multistrap or earlier stage fails silently or partially completes, skipping creation of subdirectories like proc, dev, sys. The script assumes they exist during the mount phase.

---

💡 Optional: Patch the Build System to Avoid It in Future

You can make the build process safer by editing the file:

OpenNetworkLinux/make/rfs.mk

And before the mount -t proc and mount -t devtmpfs, insert:

mkdir -p $(ROOTFS_DIR)/proc
mkdir -p $(ROOTFS_DIR)/dev

This prevents the issue from coming up again on clean builds.

---

Let me know if you're still stuck after this, or if you want to skip RFS creation altogether and only build ONL packages.

nope still the same problem:

E: Some index files failed to download. They have been ignored, or old ones used instead.
