Hi,

I second that.
I understand the feature fr= om a security standpoint, and i suppose i doesn't hurt as an added secu= rity layer. However, being able to configure it simply configure it through= a (read only,root owned) configuration file would have helped me in the si= tuation i was in when i originally posted this question. I am glad it spark= ed this discussion .

If an evil-intended someone achieves to modify this file by getting roo= t write privilege, well there's much worse he/she could do than modifyi= ng kdesu's path don't you think ?.

Regards,

Anders,

Its not the "why not lock the door" issue I think that Ossi is co= mmenting on,
but rather the fact that this is completely UN-CONFIGURABLE. If I want this=
feature as a paranoid user, it should be managed by a configuration file th= at
is read only versus plain hardcoding paths in the code. This way if _I_ don= 't
want/need it, I can set my system up as I want without patching the code unnecessarily.
