## ALPINE LINUX PACKAGE SOURCES

All components are built from Alpine Linux packages. Alpine's build system (abuild) fetches sources from upstream. You can obtain the exact source packages used in TermOS through:

### Alpine Package Repository
- **Repository**: https://gitlab.alpinelinux.org/alpine/aports
- **Browse Packages**: https://pkgs.alpinelinux.org/
- **Git Clone**: `git clone https://gitlab.alpinelinux.org/alpine/aports.git`

### Finding Specific Package Sources
Each Alpine package's APKBUILD file contains the upstream source URL. Example:
```bash
# Clone Alpine repository
git clone https://gitlab.alpinelinux.org/alpine/aports.git
cd aports

# View package source definition
cat main/linux-stable/APKBUILD
```

---

## OBTAINING SOURCE CODE FOR YOUR SPECIFIC TERMOS BUILD

To get the exact source code versions matching your TermOS installation:

### Method 1: Check Package Versions
```bash
# On your TermOS system, list installed packages with versions
apk info -v | grep -E 'linux-|grub-|networkmanager'

# Get detailed package info including source
apk info -a package-name
```

### Method 2: Download from Alpine Mirrors
```bash
# Download source package from Alpine
apk fetch --source package-name
```

### Method 3: Build from APKBUILD
```bash
# Get APKBUILD from Alpine aports repository
# and build from source using abuild
abuild fetch unpack
```

## ADDITIONAL COMPLIANCE INFORMATION

### Written Offer (GPL v2 Section 3b, GPL v3 Section 6b)

For any GPL-licensed binary you receive from TermOS, you are entitled to receive the corresponding source code. This document serves as our written offer to provide source code.

**Valid for**: 3 years from the date of TermOS distribution
**Source availability**: All source code is available at the upstream URLs listed above
**Cost**: No charge beyond the cost of physically performing source distribution

### Modified Components

TermOS does not modify the source code of GPL-licensed components. All components are built from upstream sources using Alpine Linux packaging (APKBUILD files), which add compilation flags and packaging metadata but do not modify the underlying source code.
