Is it wise to change permissions ?
I have logins setup for each member of my family. If I download a new wallpaper that my kids might like to use, I need to put it in /usr/share/wallpapers for them to have access to it.
However, I do not have write permission to that directory, instead I have to change to su, copy the files and change back.
Would it be unwise to change the permission of that directory so that I can write to it, or would I be defeating the purpose of the security?
