The detail in the IDS event generated locally on the collector isn't
complete. Under "Target" there is a "Target file current" block. The
"Name" value shows up as: "/" but the "Path" value is "/boot/".

The corresponding audit event is below.

node=audit type=PATH msg=audit(09/16/2009 20:26:54.945:271) : item=1
name=/boot/test inode=16 dev=08:01 mode=file,644 ouid=root ogid=root
rdev=00:00 obj=unconfined_u:object_r:boot_t:s0 
node=audit type=PATH msg=audit(09/16/2009 20:26:54.945:271) : item=0
name=/boot/ inode=2 dev=08:01 mode=dir,755 ouid=root ogid=root
rdev=00:00 obj=system_u:object_r:boot_t:s0 
node=audit type=CWD msg=audit(09/16/2009 20:26:54.945:271) :  cwd=/root 
node=audit type=SYSCALL msg=audit(09/16/2009 20:26:54.945:271) :
arch=x86_64 syscall=open success=yes exit=3 a0=7fffbe53d9c3 a1=941
a2=1b6 a3=386016d12c items=2 ppid=2275 pid=2448 auid=root uid=root
gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root
tty=pts0 ses=1 comm=touch exe=/bin/touch
subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
key=ids-file-hi 

Maybe the 2 "PATH" components confused the plugin code?
