check_disk: option to ignore reserved spacerefs/pull/22/head
This commit add a runtime option to ignore the root-reserved space when calculating perfdata. Before / after: ./check_disk -w 2% -c 1% /home ./check_disk -w 2% -c 1% -f /home DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;18401;18589;0;18777 DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;17466;17644;0;17823 Well, it doesn't really give me more space :) but the perfdata are a little bit more coherent. Note that there are still a rounding issue on the percent calculation (cf calculate_percent() comments, taken from coreutils 'df' command). 272/17823 -> 1.526% Since the warning/critical/min/max data are usually not saved in RRD DB, you can activate the option without seeing landslides in the graphs.
