README (3049B)
1 To compile this, you need to have libowfat (http://www.fefe.de/libowfat/)! 2 3 Each service gets its own directory under /etc/minit (change this in the 4 source, it's a #define right at the start of minit.h). 5 6 Each service directory can contain the following files/symlinks: 7 8 depends 9 10 a plain text file containing a service name per line. 11 Example: /etc/minit/sshd/depends could contain "network". 12 Each of these services will be started before this service is 13 started. If you need to wait for static initializations to 14 complete, use the sync flag. 15 16 run 17 18 a symbolic link to the program name. No hard link, because argv[0] 19 for the programs is created by extracting the part after the last 20 slash in the contents of the symbolic link. 21 Example: "/usr/bin/sshd" would be run with argv[0]="sshd". 22 23 params 24 25 a plain text file containing command line parameters for the 26 service, one parameter per line. No shell expansion is done. If 27 you need shell expansion, have run point to a shell script instead 28 of the real daemon. Note: Have the shell script exec the daemon 29 instead of simply running it to save system ressources. 30 31 respawn 32 33 touch this file to make minit respawn the process when it dies. 34 This should be touched for getty and network servers. 35 36 sync 37 38 touch this file to make minit wait until the service ends. sync is 39 mutually exclusive with respawn. This is meant for static 40 initializations like "ifconfig". 41 42 log 43 44 if this directory exists, it is taken as service and minit creates 45 a pipe between stdout of this service and stdin of the log service. 46 If the log service can not be started, this service will block if it 47 writes to stdout. File descriptors will be reused, i.e. if the log 48 process dies and is restarted, no log entries will be lost and there 49 will be no SIGPIPE. 50 51 nice 52 53 a plain text file containing the value to add to the nice level via the 54 nice systemcall. 55 56 in 57 58 this file is used for stdin. 59 60 out 61 62 this file is used for stdout and stderr. 63 e.g. a symlink to /dev/null 64 65 66 Please see http://cr.yp.to/daemontools/multilog.html for a very good 67 logging tool. 68 69 minit will try to run the command line arguments as services. The 70 kernel passes its arguments to init. That means you can for example 71 have a service /etc/minit/sos-shell that starts a /bin/sh and then use 72 LILO to boot "bzImage sos-shell". minit will then run that service. 73 If none of the services worked (or none were given), minit will spawn 74 the service "default". The normal way to configure minit is to have 75 default be an empty service and just list all the services you want 76 minit to start at boot time in default/depends. 77 78 Other special services (besides "default") are "ctrlaltdel" and "kbreq". 79 ctrlaltdel will be run when the console user presses ctrl-alt-del and is 80 meant to reboot the computer. kbreq is the keyboard request, which 81 can be mapped using loadkeys. On my box, it is on Alt+Arrow-Up. I use 82 it to shut down the computer.
