The files referenced in this document, all appear on autoinst.acs.uci.edu. "###" below, is meta-syntax for a three digit number. The numeric prefixes change too often to update them in this document each time. Directories: /auto_install/OSF-1 - DEC alpha-specific stuff /auto_install/Irix - SGI specific stuff /auto_install/Solaris-2.5 - Solaris 2.5 specific stuff. /auto_install/Solaris-2.4 - Solaris 2.4 specific stuff. /auto_install/generic-after - Things common to Irix, DEC OSF/1, Solaris 2 and SunOS 4 are under here. /auto_install/generic-after/each - Where changes to the autoinstall procedure are usually made. The /auto_install/generic-after/each directory contains many files, one for each (variety of) change made to a system. The files are executed in ascii order, and are named with an initial three digits, by convention. Among the most frequently edited files are: ###-domainname The OSF/1 and Irix autoinstalls don't depend on NIS. The downside is, we have to guess the NIS domainname. That's done here with a case. OSF/1 and Irix only. ###-is-NIS-server If a machine is to be initialized as an NIS server (slave or master), add a case for it here. ###-mail-config Defines what hosts are mail hubs, what are mail clients, and the relationship between clients and hubs for a given domain. If a machine is totally standalone, don't define anything here. If there are two or more machines in the domain, then YP.hnet.uci.edu makes a good example - anything simpler is perhaps a tad over-simple. ###-use-cde Choose whether or not you want a machine to use CDE. Mutually exclusive with xdm. ###-autocad This makes a nice example of doing an application thru autoinstall. The vast majority of the files are on an external disk. Originally written by Mike Sorenson. ###-cap-server If a machine is to be a CAP server, add a case for it here. ###-groupleader Controls the configuration of "gsu" ###-host-mounts For host-specific entries in $FSTAB (except for mail spools, which are usually more generalizable, and done in ###-mail-spool) ###-httpd Set up a skeletal Web server, for selected hosts. ###-mail-spool Provide for an NFS mount of the mail spool. SOE uses a symlink into an indirect map. ###-misc-symlinks Catchall for symlinks ###-mrouted Set up an mbone router on selected hosts ###-pcnfsd Set up an rpc.pcnfsd on selected hosts ###-popper Set up a pop daemon (inetd-invoked) on selected hosts ###-rhosts If a workgroup wants to have machines root-rsh'able from a common host, this is the place to set that up. Note that this is an unlikely security hole, but a serious one if exploited. ###-root-password For setting root passwords. Does give a default root password, if none is specified. Also used for "root2" accounts. ###-sparcprinter Set up a sparcprinter. NOT COMPLETE. Contains comments that should provide info required to finish someday. ###-swapfile Set up a swap file (OSF/1 appears to contain some hooks for doing this, but it sounds like swapping to a file is not yet supported in 3.0). I haven't looked into this for Irix. ###-xdm A nice selection of xdm options, provided by John Ward. ###-login-restriction Sets up netgroup-based login restrictions on selected hosts. ###-sendmail Customize sendmail setup, for a set of hosts pointing at a particular mail spool. Environment variables useable from within a segment of "after": OPSYS1 Operating System - generic form. Eg "SunOS" or "OSF1" OPSYS2 Operating System - specific form. Eg "SunOS-5.5" or "OSF1-3.2c" ROOT Root of the filesystem tree, while "after" is running. May be "/" sometimes, something else others. Please don't write code that depends on what that "something else" is - just assume $ROOT is where the new system's stuff starts. DIR Root of a tree of auxiliary files, present when "after" is running. interfaces The machine's network interface names. ipaddresses The machine's IP addresses. subnets The subnets on which the machine sits name The machine's DNS name domain The machine's DNS domain (not the YP/NIS domain) RCDIR The directory underwhich the rc* files are found. Basically, /etc on everything but OSF/1 - where it's /sbin FSTAB The "fstab" file - /etc/vfstab on SunOS 5, /etc/fstab on everything else. Auxiliary scripts available on the path, during after's execution. There are tons of examples in the "each" directory - "grep" for them. add-acct Add a local account. Best avoided. add-aufs Add a CAP fileservice add-gl Add a groupleader entry add-to-gl Add a user to a (possibly not-yet-created) groupleader entry add-group Add an entry to /etc/group. Best avoided. add-line Add a line to an arbitrary ascii file, if the line is not already present in that file. add-login-group Add a login restriction. add-lwsrv Export a unix printer for CAP (mac) users cap-init Cap initialization. Needed on each cap server. cap.printers Add an entry to the "cap.printers" file. dcslib-cron Add an entry to dcslib's crontab ftu Add a restriction on who can use ftp hosts Add a $ROOT/etc/hosts entry inetd-ent Add an inetd entry is-initial-install Returns true if autoinstalling, false if running "run-after". Usually best avoided, but needed in some limited cases. make-dir Create a directory (and the entire path to it). Doesn't give an error if the directory already exists. make-link Create a link. Doesn't create the entire path. Doesn't give an error if the link already exists. nfs Add a $FSTAB entry for a static NFS mount. Independent of vendor-dependent $FSTAB syntax. See also the "vfs" script. rhosts Add a $ROOT/.rhosts entry root-cron Add a cronjob for root root-pw Define a root password root2 Create a "root2" account, and add a password for it. Avoid this; try to use the gsu/groupleader stuff instead. services-ent Add an entry to $ROOT/etc/services shared-cap-volume Add a shared volume for CAP (mac) users vfs Add an entry to $FSTAB. Not independent of $FSTAB syntax. Usually used for local disks. See also the "nfs" script. http://www.nacs.uci.edu/support/dcs/automation/tailoring-after.html
