System Boot and Error Message Format Changes

If msgid is set to 0 in the log.conf file, there are no changes in the message format. If msgid is set to 1, there are two changes in the message format:

1. The text of the message is preceded by a message ID that looks like this:

   [ID msgid facility.priority]

   For example:

   [ID 123456 kern.notice]

   The msgid identifier is described in the man page msgid(1M). The facility and priority identifiers are described in the man page, syslog.conf(4).

2. If the message originated in the kernel, the kernel module name is displayed instead of just 'unix.'

   Previous message format:

   Oct 1 14:07:24 mars unix: alloc: /: file system full

   New message format:

   Oct 1 14:07:24 mars ufs: [ID 845546 kern.notice] alloc: /: file system full
