[Message part 1 (text/plain, inline)]

I put my name as Tsarina Baelarina Nina, as opposed to my real name. It 
created the correct home profile, but also included the two extra empty 
directories in my home directory as included in the attachment for 
proof. I think I remember reading something about camel casing for user 
names on the system, as in the name can't start with a capital letter, 
but I thought you could get away with spaces if you escaped the strings 
properly \(space).

I can reproduce with the attached configuration.
I'm wondering what software is creating these 'Baelarina' and 'Nina'
subdirectories of '/home/Tsarina Baelarina Nina/' ... is it Guix, is it
GDM, is it the GNOME desktop ...?

I'm not very familiar with this part of the system, but I think that
user home directories are created here, in ((gnu build activation)
activate-users+groups):

https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/build/activation.scm?id=ff093f5739a61e77b296feccc48d260b9bb574c0#n160

I tried to create a minimal reproducer by editing the user-account in
'gnu/system/examples/bare-bones.tmpl' with the name "Tsarina Baelarina
Nina".

Guix did the right thing, and created a single directory called
'/home/Tsarina Baelarina Nina/', without the bogus subdirectories.

So, if it is caused by Guix, it's not the basic user-account tooling
that does it.
