9legacy

9legacy is a continuation of Plan 9 from Bell Labs.

Usage

Run Plan 9 on QEMU

1. Build empty directory hierarchy

Empty directories can't be committed to a Git repository.

The following script will build the empty directory hierachy, identically to the content of the original Plan 9 CD image.

Run:

./boot/mkdirs

2. Install binaries

This step requires the 9660srv command from plan9port, so the CD image will be mounted using the Plan 9 ISO 9660 extension.

The following script will download the last 9legacy CD image and extract the 386 and amd64 binaries to the root of the Git repository.

Run:

./boot/getbin

3. Run QEMU

The following script will build u9fs from sys/src/cmd/unix/u9fs, if needed, then run QEMU.

Run the following script to build u9fs and run QEMU:

./boot/qemu

Rebuild boot/pxeboot.raw

This Git repository already includes a prebuilt boot/pxeboot.raw boot loader.

This step is necessary only if you want to rebuild boot/pxeboot.raw, for example, after making changes to the boot loader.

1. Reduce the size of 9bootpbs

Apply the following patch to reduce the size of 9bootpbs:

patch -p1 boot/9-pcboot-boot.diff

2. Rebuild 9bootpbs

On Plan 9, run:

mkbootpbs

3. Rebuild pxeboot.raw

On Plan 9, run:

mkpxeboot

We thank Russ Cox, who made the scripts to easily boot a Plan 9 file hierarchy on QEMU.
