[PATCH v2] Control over when package init scripts are run

[Gary Thomas <gary@mlbassoc.com>]

[-- Attachment #1: Type: text/plain, Size: 782 bytes --]

When a package is built, some installation scripts must be
performed on the target.  In the case of a complete image,
these scripts are run by a separate step at init time, but
only during the first boot (other package install scripts
can just be run when the package is installed on the target).

This patch lets the distribution (or user) decide when these
postponed install scripts should run.  The default is normally
near the end of init, but there may be times when it's beneficial
to run them earlier so the "when" can be overridden.

Subject: [PATCH] Control over when package init scripts are run

When a package is built, some installation scripts must be
performed on the target.  In the case of a complete image,
these scripts are run by a separate step at init time, but
only during the first boot (other package install scripts 
can just be run when the package is installed on the target).

This patch lets the distribution (or user) decide when these
postponed install scripts should run.  The default is normally
near the end of init, but there may be times when it's beneficial
to run them earlier so the "when" can be overridden.
