I already use the /etc/profile to set the PATH, but I think, /etc/profile is
only used on login, isn't it?

The busybox uses ash, but an .ash* file does not exist.
If I create the .ashrc and export ENV=/var/tmp/.ashrc it works, but to
export ENV, I again need the /etc/profile.
This works, but only with ssh, not with scp, due to the missing login.

I found this sentence at

"Environment variables set in a shell script will not have any effect to any
parent process."

I think this is my problem, because the $PATH in an ssh session seems to be
a different one than the $PATH I get executing echo $PATH without logging

ssh root at fritz.box 'echo $PATH' :    /usr/local/bin:/usr/bin:/sbin:/bin

echo $PATH inside the session :     /sbin:/bin:/usr/sbin:/usr/bin:/var/tmp

In the link it is said that changing the boot-arguments would help, but this
is not practicable since I only change scripts after the machine has booted.

I thought it would be easily possible to change a line in the code to add
the correct path to scp on the router.
If so, could you tell me the file where I have to search?
