The preferred method of service 28management is via the Service Management Facility; to read more about 29SMF, consult smf(5). 30 31File names in rc?.d directories are of the form [SK]nn<init.d filename> 32where 'S' means start this job, 'K' means kill this job, and 'nn' is the 33relative sequence number for killing or starting the job. When 34executing each script in one of the /etc/rc[S0-6] directories, the 35/sbin/rc[S0-6] script passes a single argument. It passes the argument 36'stop' for scripts prefixed with 'K' and the argument 'start' for 37scripts prefixed with 'S'. There is no harm in applying the same 38sequence number to multiple scripts. In this case the order of 39execution is deterministic but unspecified. It is recommended that 40scripts be hard-linked from the same file stored in /etc/init.d/. 41 42On earlier Solaris releases, a script named with a suffix of '.sh' would 43be sourced, allowing scripts to modify the environment of other scripts 44executed later. This behavior is no longer supported; for altering the 45environment in which services are run, refer to the SMF documentation. 46 47Legacy services are reported by the default svcs(1m) output, and (where 48appropriate) the utility's '-p' option. This reporting assumes a 49behavior as described above, such that each 'S' script has a suitable 50matching 'K' script, and they are both hard linked to a script in 51/etc/init.d/. If this is not the case, legacy service reporting may not 52operate accurately; under all circumstances, the scripts are always 53executed as described above. 54 55The run-levels operate as follows: 56 57s/S 58 59 Read /etc/rcS.d/README for details. This run-level corresponds to 60 the milestone svc:/milestone/single-user:default. 61 620/5/6 63 64 All /etc/rc0.d/K* scripts are run, followed by all /etc/rc0.d/S* 65 scripts. The S* scripts should only be used for cleanup during 66 shutdown. 67 681 69 70 If the system was in a higher run-level, all /etc/rc1.d/K* scripts 71 are run. Regardless of the previous run-level, all /etc/rc1.d/S* 72 scripts are run. 73 742 75 76 Read /etc/rc2.d/README for details. This run-level corresponds to 77 the milestone svc:/milestone/multi-user:default. 78 793 80 81 Read /etc/rc3.d/README for details. This run-level corresponds to 82 the milestone svc:/milestone/multi-user-server:default. 83 84
