I've installed Linux Mint on my old laptop.
I created a username with the temporary use in mind so it is not that good name and I want to change it.
I know how to change username and rename the home-directory + username's group.
I just tested this thing on a new account with nothing installed or configurated, so it did not show any problems....
But I have tons of stuff on my own user and I want to know if there are some caveats to changing username.
Like some files that use username for different things, does the system automatically link the username changes to all these dependencies or do I have to manually use symlink between the old and new usernames? Or something similar?
Can username change cause that some programs/system-files dont work because they are looking for the old name or anything else like that?
