"with full power of debian repo behind it" isn't possible with a <100 MiB system, where already the kernel (with all modules) takes half of it, then + initramfs etc, and not to forget systemd (practically required for large parts of Debian packages). The compressed images are however only slightly >100 MiB usually, depending on whether a separate /boot FAT partition is used or not. Another larger part of space is used for full WiFi support, related firmware especially. When creating or converting an own image, it is possible to skip WiFi, but for best compatibility with headless use cases, it is included in the provided downloads: https://dietpi.com/docs/hardware/#make-your-own-distribution https://dietpi.com/docs/hardware/#make-your-own-distribution
