Niels Sascha Reedijk dfb36b35b9 Installer: fix 'clean install' over existing installation.
Whenever the target of an installation is a partition that is not empty, the
Installer prompts the user whether they would like to continue with a 'clean
installation', i.e. an installation that clears out the system folder,
excluding the settings, and cleanly installs the assets in the source's
system folder. At all other locations the source data is merged, meaning that
the source version is copied in place.

The logic that clears out the existing /system/ directory stopped working. This
change moves that logic from the copying process, to where it is run before any
file is copied. The added advantage is that the system folder is now properly
cleaned up, also stray files under the system folder will be removed.

This change does not change the logic of what constitutes a 'clean install'.
There are arguments to be made that it should potentially also drop the
settings files, as well as clean out the user's home folder for stray
add-ons, but that really is different functionality, and at this points I
think the requirements for that are not yet fleshed out.

The change was manually tested.

Fixes #16092

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
