Added -i/-I to ignore pathes/partitions based on regular expressions
Added check_disk -A selecting all filesystems -E option must now be passed before -p or -r/-R Passing -E after -p or -r results in UNKNOWN state Fixed bug when mixing case sensitive and insensitive regexes git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1786 f882894a-f735-0410-b71e-b25c423dba1c
