Hi All,

I apologise even though my previous posts were not intended to offend
or humiliate. As a coder supporting Devuan, my first preoccupation is
to get code to do what it is intended for. I am giving support by
coding to Devuan in my now very limited free time.

Since .desktop files are not user data files and are also small text
files, I decided in favour of replacing the entire file instead of
trying more complicated solutions to replace only what was changed.
The overhead if any should not be noticeable for users as the
rewritten files are very small.

Edward
