| - | ===== Getting the Installer Buildscripts ===== | + | ==== Remove the Tools Directory ==== |
| - | Navigate to /opt/culfs and download the installer buildscripts from the Cucumber Linux mirror: | + | The ''/tools'' directory is no longer needed, so remove it to ensure that the tools located there do not impact phase 4 and update the PATH variable accordingly. |
| - | cd /opt/culfs | + | rm -rf /tools |

| - | Create a symlink to the directory containing the binary packages. Replace ''$CUCARCH'' with the architecture you are building for (''i686'' or ''x86_64''). If you are building for both architectures, create a separate symlink for each one. | + | Proceed to build the phase 4 packages. Similarly to phase 3, this entire process can be automated with portmake. Note that this will take a //very long// time (even longer than phases 1. 2 & 3). |

| - | If desired, rebuild the initrds. This step is optional; if you skip it, the prebuilt initrds in the official Cucumber Linux source tree will be used instead. See the file installer/README for instructions on this. | + | exit |
| - | ==== Build the ISOs ==== | + | ===== Getting the Installer Buildscripts ===== |
| - | Cd to the installer/iso directory. | + | Navigate to /opt/culfs and download the installer buildscripts from GitHub: |
| + | |||
| + | cd /opt/culfs | ||
| + | git clone https://github.com/cucumberlinux/installer.git | ||
| + | |||
| + | ===== Building the Installer ===== | ||
| - | cd installer/iso | + | Enter the installer directory. |
| - | If you are not building the ISOs for every architecture, you will need to modify iso.buildscript. If you are building for all architectures you can skip this step. | + | cd installer |
| - | In iso.buildscript, find the line that reads: | + | Run the build-iso.sh script, setting some special variables. |
| - | for a in x86_64 i686; do | + | PORTSDIR=/opt/culfs/chroot/usr/ports PKGDIR=/opt/culfs/chroot/opt/packages ./build-iso.sh |
| - | Delete the architectures that you are not building from that line. | + | This will the installer ISO file and place it in /tmp. |
| - | Finally, run iso.buildscript. This will build your installer ISO images and place them in /tmp. | + | ====== The End ====== |
| - | ./iso.buildscript | ||
