It is a very generic tool, so it +could potentially be used to generate anything from rescue systems, +to install disks, to special interest live CD systems, and who knows what +else. Simply put, if it involves Arch on a shiny coaster, it can do it. + + +- Alright, so how does one install it? + +First off, Archiso has some dependencies: + - mkinitcpio + - cdrkit + - squashfs-tools + - aufs2 (only needed in target media) + - aufs2-util (only needed in target media) + - devtools for mkarchroot + - syslinux + - nbd + - mkinitcpio-nfs-utils + +Archiso itself can be installed with the handy dandy included Makefile, +and the incantation 'make install'. + + +- Great, so how do you use this thing? + +The heart and soul of Archiso is mkarchiso. All of its options are +documented in its usage output, so we won't go into detail here. +Instead, let's go over the general process. + +The first thing you should probably do is create a directory to work +in, and cd to it. This'll help keep things organized. Next, you'll want +to create a mkinitcpio config file that suits your needs. Typically this +means modifying whatever hooks you want. A typical set of hooks for +archiso looks something like this: + +HOOKS="base udev archiso pata scsi sata usb fw pcmcia filesystems usbinput" + +It's probably worth mentioning that hardware autodetection and things +of that nature do not belong here. Only what's necessary to get the system +on its feet, and out of the initcpio really belong here, fancier stuff +can be done on the booted system anyway. + +You'll also want to create a list of packages you want installed on your +live CD system. A file full of package names, one-per-line, is the format +for this. Typically you'll want BASE and a kernel as a bare minimum, but +you're free to install whatever else you want. This is *great* for +special interest live CDs, just specify packages you want and gogogo. + +The last item of importance is what are called addons. Basically this +means any other crap you might want to include on your live CD, including +binary package repos, special configurations, random files, we don't +know, be creative. mkarchiso expects them all to be put in a single +directory, with an fstab-like config file. Currently two types of addons +are supported, squashfs images that get layered onto the root union, and +plain directories which can be bind mounted anywhere under the root. + +If you want to add a squashfs union layer: +- Set up whatever you want to include in a separate directory someplace, + as if that directory was / . Then run mksquahfs on it, and copy the + created image to your addons directory. +- Add an entry to your addons config file (which must be named 'config', + by the way). Typical squashfs entries look like this: + live_overlay.sqfs / squashfs + Where the first component is the path to the image relative to your + addons directory, the second is the mountpoint (irrelevant for + squashfs, they will all get layered at /) and of course the third + component is the type. +- Be aware that the order of entries on the config matters! Entries will + be layered on top of one another, later entries are mounted _UNDER_ + earlier entries (an unfortunate counterintuitive result of the way we + have to mount the unions). + +If you want to add plain directories to bind mount: +- Set up your directory somewhere, and copy it to your addon directory. +- Add an entry to your addons config file, example entry: + core /packages bind + where the first component is the path to the directory relative to + your addons directory, the second component is where you'd like it + bind-mounted relative to the live CD's root filesystem, and the last + component is the type. + + +- How can build installation mediums like provided by Arch Linux? + +- Just follow these next steps as root. +- Note that mkarchroot is optional, but with it, will ensure to have + a clean enviroment for building isos. +- This clean chroot, will take about 400MB (+130MB with all needed tools). +- After make, max space usage is about 2GB. +- In last step instead of just execute make, can be more selective: + Execute "make net-iso" or make "core-iso". + Do not execute make net-iso after make core-iso, otherwise net-iso + will be really a core-iso. + + +pacman -S devtools --needed +mkarchroot /tmp/somedir base +mkarchroot -r bash /tmp/somedir +# vi/nano /etc/pacman.d/mirrorlist and uncomment your prefered mirror. +pacman -S git squashfs-tools syslinux devtools cdrkit make nbd mkinitcpio-nfs-utils +cd /tmp +git clone git://projects.archlinux.org/archiso.git +cd archiso/archiso +make install +cd ../configs/syslinux-iso/ +make + +Done! + +vim: textwidth=72 |
