Author: tzafrir
Date: Tue Nov 21 15:23:08 2006
New Revision: 1632

URL: http://svn.digium.com/view/zaptel?view=rev&rev=1632
Log:
Rephrase/rewrite zaptel.init using zaptel-helper functions:
 * Much simpler modules loading (used only in the Debian case.
 * The recusrsive unload_modules instead of the unrelible RMODULES list.
 * No explicit sleep (only sleep command is 'sleep 1' in wait_for_zapctl).
 * Should work better with the Xorcom Astribank.
 * Check with -r before sourcing a file.
 * Debian scripts run with -e. No line there should fail for no good reason.
