From 9a51af88aa234e2ceb6a1daf830f63a11202beb3 Mon Sep 17 00:00:00 2001 From: Jakub Jankowski Date: Tue, 21 Nov 2017 02:38:53 +0100 Subject: rc.inet1*: Simplify virtif_* code, add note to example config There is a built-in way of counting the number of elements in an array: ${#arrayname[@]}. Use this, and the fact that "for i in $(seq 0 -1)" will not evaluate body of the loop even once, to simplify code and get rid of virtif_determine(). While at it, add a note to rc.inet1.conf mentioning the necessity of keeping array indexes monotonically increasing (from 0), otherwise the code will fail (so would the original code).
