update-metainit

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME

       update-metainit - Generates init scripts

SYNOPSIS

       update-metainit [--remove initname [--purge] ]

DESCRIPTION

       Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
       declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
       trator.

       If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
       a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
       effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.

OPTIONS

       --remove initname
	   This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.

       --purge
	   Only usable with --remove. Will remove the generated files even if modified.
