The Giant ANTS for Plan 9 are a collection of software for making Plan 9 systems more flexible and reliable by leveraging the power of namespaces.
The main component is a modified kernel which needs no root fs at boot. It creates an always available ram/paq rooted namespace accessible by cpu(1) from which the user may launch conventional namespaces. Additional tools allow the user to reroot quickly to different namespaces and create hubs of persistent rc shells shared between all machines on a grid.
ANTS is compatible with existing x86 Plan 9 installations. The ANTS kernel and tools modify startup and create new capabilities, but do not change the standard user environment. You can install the ANTS kernel and tools directly to a fresh install from the 9front or Bell Labs .iso, just add the 9ants or 9pcram.gz kernel and optional tools.tgz to your 9fat partition and edit plan9.ini as needed. Full install/use documentation is also provided.
ANTS is a modular toolkit. Many of the namespace modifying scripts, the hubfs shell multiplexer, and the rio variant "grio", do not depend on the kernel modifications. The kernel modifications for bootup and for writable /proc/*/ns are independent from each other. ANTS can be used as a self-sufficient micro-distribution of Plan 9 around 6mb in size.

After bootup reaches the shell prompt, type "gui" to start rio on the local display. cpu (1) service is also available on port 17060 as user glenda with default password "rootless". If a cdrom is attached, the cd bootup option will use the cd termrc as well as providing an independent namespace available via cpu.
