Re: [Linphone-users] Bug report: Linphone replaces a link to .linphonerc with actual file

[Gautier Pelloux-Prayer]

Hi,

Indeed you are right symlinks should not be overridden. I made a tentative of 
patch in linphone master:

6ce479b 2015-07-28 11:48:32 +0200 Gautier Pelloux-Prayer  lpconfig.c: when 
reading linphonerc, we must follow symlinks

This will probably break some other OS but the idea is there ;-). If you can 
compile it, let me know if it's working as expected for you. Otherwise, it will 
be ready for next release which is not planned yet.

Cheers,
