The /sbin/rc2 Script

The /sbin/rc2 script runs the /etc/rc2.d scripts to perform the following tasks, grouped by function:

Local system-related tasks:

• Mounts all local file systems if the previous run level was S

• Enables disk quotas if at least one file system was mounted with the quota option

• Saves temporary editor files in the /usr/preserve directory

• Removes any files and subdirectories in the /tmp directory

• Starts system activity data collecting, system accounting, and system auditing, if configured

• Starts the system logging daemon (syslogd), sets the default dump device, and rotates the /var/adm/messages file

• Sets the default scheduling class if the /etc/dispadmin.conf file exists

• Starts LP print service (lpsched) if a local printer is configured and cleans up the print queue

• Configures power management, if appropriate

• Starts the utmpd daemon

• Starts the cron and vold daemons

• Configures serial device stream

• Configures WBEM services

• Syncs volumes, if required, and starts the mdmonitord daemon to monitor the physical components of the volumes

• Starts the CDE desktop login process, dtlogin, if appropriate

Network service or security-related tasks:

• Configures the network interfaces, sets ifconfig netmask, and configures network routing, if appropriate

• Starts network service (inetd and rpcbind) daemons

• Starts the logical link controller (llc2), if configured

• Sets the name service domain name, starts various name services daemons, depending on if the system is configured for a name service, and whether the system is a client or a server

• Starts the keyserv, statd, lockd, and xntpd daemons, if appropriate

• Mounts all NFS entries

• Configures the Solaris Network Cache and Accelerator (NCA) and NCA logging, if appropriate

• Starts the Solaris PPP server or client daemons (pppoed or pppd), if configured

• Starts LDAP cache manager (ldap_cachemgr), if configured

• Starts directory server (slapd) daemon, if configured

• Starts DNS (in.named) daemon, if configured

• Starts Service Location Protocol (slpd) daemon, if configured

• Configures system resource controls and system pools if the /etc/rctladm.conf and /etc/pooladm.conf files exist

• Starts the cachefsd, automount, and sendmail daemons, if appropriate

• Starts the htt_server process

Install-related tasks:

• Configures the boot environment for the Live Upgrade software upon system startup or system shutdown

• Checks for the presence of the /etc/.UNCONFIGURE file to see if the system should be reconfigured

• Reboots the system from the installation media or a boot server if either /.PREINSTALL or /AUTOINSTALL exists

Hardware-related tasks:

• Starts the Sun Fire 15000 key management daemon (sckmd), if appropriate

• Starts the Sun Fire 880 Dynamic Reconfiguration daemon (sf880drd), if appropriate

• Runs the flash PROM update script

• Configures any graphic frame buffers or graphic accelerators

• Runs the FCode interpreter daemon (efdaemon), if necessary

Transitions the following services between run-level changes:

• Apache (tomcat)

• Boot server (in.rarpd), (rpc.bootparamd), or (rpld)

• DHCP (in.dhcpd)

• Kerberos KDC (krb5kdc ) and Kerberos administration (kadmind)

• Mobile IP (mipagent)

• NFS server (nfsd), (mountd), (nfslogd)

• Samba (smdb) and (nmdb)

• Secure shell (sshd)

• Solstice Enterprise Agents (dmispd) and (snmpXdmid)

Many of the system services and applications that are started at run level 2 depend on what software is installed on the system.
