# ISO Build Rules
|
||
|
||
## Verify package names before use
|
||
|
||
ISO builds take 30–60 minutes. A wrong package name wastes an entire build cycle.
|
||
|
||
**Rule: before adding any Debian package name to the ISO config, verify it exists and check its file list.**
|
||
|
||
Use one of:
|
||
- `https://packages.debian.org/bookworm/<package-name>` — existence + description
|
||
- `https://packages.debian.org/bookworm/amd64/<package-name>/filelist` — exact files installed
|
||
- `apt-cache show <package>` inside a Debian bookworm container
|
||
|
||
This applies to:
|
||
- `iso/builder/config/package-lists/*.list.chroot`
|
||
- Any package referenced in `grub.cfg`, hooks, or overlay scripts (e.g. file paths like `/boot/memtest86+x64.bin`)
|
||
|
||
## Example of what goes wrong without this
|
||
|
||
`memtest86+` in Debian bookworm installs `/boot/memtest86+x64.bin`, not `/boot/memtest86+.bin`.
|
||
Guessing the filename caused a broken GRUB entry that only surfaced at boot time, after a full rebuild.
