I tried to use my own nixpacks.toml to maybe have a bit more granular control

# nixpacks.toml

[phases.install]
cmd = "pnpm install"

[phases.build]
cmd = "pnpm migrate_build"

[phases.start]
cmd = "pnpm start"

[static_cache]
paths = []

I get this

Can you check if some processes are using the directory with lsof +D .next/cache and also is the directory a mount point df -h. Also, it would help a lot with debugging if you could provide a sample repository.
