- Advanced Namespace Tools for 9front - This is a toolkit of additions and modifications to Plan 9.  It isdesigned to make Plan 9 installations, on single machines or onnetworks, more flexible.  ANTS has: * A modified boot process which creates an isolated administrativenamespace independent of any root fileserver. * A modified kernel which accepts manipulation of process namespacevia writes of standard namespace operations to the /proc/PID/ns files * Kernel mod and rc patch to allow rfork V into a new /srv namespace * Scripts for moving between and systematically altering namespacessuch as "rerootwin" which is similar to chroot in unix and keeps theterminal devices at /mnt/term active. * Optional fossil/venti support with administrative scripts forprogressive backup/replication and maintaining a log of rootscores * Hubfs 9p fs for networked persistent shell sessions and alightweight general purpose multiclient read/write buffered messagequeue with pipelike hubfiles * Grio modified Rio with customizable appearance for color-codednamespace grouping, user-selectable additional menu command, and hubfsintegration Most of these components are synergistic, but not interdependent.  Theuserspace programs and utilities do not generally depend on using themodified ANTS kernel. - Installing on 9front from source - Check that your 9front hg revision matched up with a compatible ANTSrevision.  The most recent tested 9front revision is the 5736 Feb2017release.  Previously tested ANTS/9front revisions are listed in theINSTALLING file.The build script has a variety of possible targets.  Abasic sequence: 	# compile everything but install nothing yet	build 9front	# install userspace components but not kernel/9fat	build fronthost 	# copy new kernel and tools to 9fat partition	9fs 9fat && cp 9ants /n/9fat && cp tools.tgz /n/9fat	# add one line to /rc/bin/termrc for gui/terminal service	echo 'home=/usr/$user; cd; . $home/lib/profile' >>/rc/bin/termrc	# edit plan9.ini	acme /n/9fat/plan9.ini	To allow you to select between kernels at boot, you can set bootfile=in plan9.ini to not provide a value.  Then at boot you will have totype "bootfile=9ants" or "bootfile=9pc" (assuming that is youroriginal kernel name) and then "boot".  You may want to set"bootcmd=plan9rc".  if you set "privpassword=" to something inplan9.ini, a cpu listener on port 17060 will be started to allowhostowner cpu/drawterm to the ants boot/admin namespace.cfg/plan9.ini has a minimal example that works with a fresh cwfsinstall to a qemu vm. You may also wish to change "rio" to "grio" in your profile. - Using 9front/ANTS - The behavior of the standard user namespace should be unchanged, apartfrom the use of grio rather rio if desired.  To access the specialservice namespace, either rcpu in (the default port is 17060) or, ifusing a terminal system, "hub hubfs" to connect to a peristent shellin that namespace.  When connecting to the service namespace viaDrawterm, add the -B flag.  From within the service namespace, you mayenter the standard namespace with this sequence: 	rerootwin -f boot	service=con	. $home/lib/profile With bootcmd=plan9rc set in plan9.ini, ANTS supports additional bootoptions, such as fossil+venti (requires installing fossil,partitioning hard drive correctly, and setting plan9.ini options.) orfully interactive boot with prompts for all options (withinteractive=yes in plan9.ini). Additional documentation found in the INSTALLING file and in the doc/subdirectory.
