I've created a Nautilus Action to edit files with sudo (gksudo) and the text editor that opens the file is always using a different configuration from the normal user.
The same thing happen when I run sudo gedit file or sudo subl file
Can I fix this or is it a security measure?
What happens in your case is that probably the configuration contains the option always_set_home which switches the home directory and thus the configuration to /root.
Solutions:
sudoedit for this purpose, which will preserve your environment. sudo visudo and comment out the always_set_home optionsudo -E gedit file to preserve the environmentI'm not aware of any security implications, but of course nasty things will happen if someone replaces the gedit configuration file with a symlink to a system file. But if you use sudo gedit it is assumed that you know what is going on on your system.
