`rootfs.size` doesn't work with latest `alpine-base:0.2.0` image as it lacks `resize2fs`

[codethief]

When I specify rootfs.size for my VM (using the default alpine-base image), Gondolin v0.12.0 fails with:

Command failed, Error: failed to resize rootfs inside guest (exit 127): rootfs.size requires resize2fs in the guest image (install e2fsprogs)

It seems the e2fsprogs dependency was added to images/alpine-base.json in commit 4652b55 but the latest alpine-base image release (v0.2.0) was weeks before that (c6efbe3), so didn't include that change.

seeing the same issue here. i believe the problem is that resize2fs is in /sbin which is not in $PATH

the same issue occurs on the host OS with build as my host stores resize2fs in /sbin

[codethief]

@khimaros I don't see any resize2fs in /sbin in the default alpine-base:0.2.0 image. Am I missing something?

I opened #140, which should resolve this issue if merged. Alpine packages resize2fs under e2fsprogs-extra, so simply releasing the change in 4652b55 won't suffice.

FYI I solved this by creating a build-config.json

{
  "arch": "aarch64",
  "distro": "alpine",
  "alpine": {
    "version": "3.23.0",
    "kernelPackage": "linux-virt",
    "kernelImage": "vmlinuz-virt",
    "rootfsPackages": [
      "linux-virt",
      "rng-tools",
      "bash",
      "ca-certificates",
      "curl",
      "e2fsprogs",
      "e2fsprogs-extra",
      "nodejs",
      "npm",
      "uv",
      "python3",
      "openssh"
    ],
    "initramfsPackages": [],
    "krunfwVersion": "v5.2.1"
  },
  "rootfs": {
    "label": "gondolin-root"
  }
}

then running npx gondolin build --config build-config.json --tag alpine-e2fsprogs-extra:latest
and then creating the vm with sandbox: { imagePath: "alpine-e2fsprogs-extra:latest" }

an upstream solution would be great though :)

i created a pi extension which automatically works around this limitation in gondolin. https://github.com/khimaros/pi-sandbox
