skeleton files in sub-directories

[Reza Alizadeh Majd]

Hi Guix, 

I want to add a series of configuration files to each user's home directory. 
for this 
I could use skeletons in operating system definitions. 

the problem is that some of these skeletons are located in sub-directories, for 
example `~/.local/share/foo/bar.cfg`. and when I run `guix system reconfigure`
I receive errors about missing parent directory (`~/.local/share/foo` in this 
example).

is there any way to create parent directories before copying the skeleton 
files? 


Thanks,
Reza
