Guillaume Nodet updated KARAF-4815:
-----------------------------------
    Description:=20
karaf script fail to locate KARAF_HOME.
on RedHat=20
REALNAME=3D`readlink -e "$0" > /dev/null 2>&1` return a blanc string
and DIRNAME=3D`dirname "$REALNAME"` return a dot.

on a side note, I suggest using $(shell comand) instead of `shell command`
I've found a solution
