I just noticed this:
--8<---------------cut here---------------start------------->8---
$ guix size ktouch | tail -1
total: 1752.4 MiB
--8<---------------cut here---------------end--------------->8---
Sounds a lot for a touch typing tutor.
Turns out ktouch references all its build-time dependencies: gcc,
glibc:static, binutils, findutils, everything. It comes from the
wrapper:

This is bad for the closure size and probably not good for application
startup time either.
The problem seems that ‘variables-for-wrapping’ in qt-build-system.scm
is too naive: it collects in XDG_DATA_DIRS all the /share directories.
Conversely, ‘data-directories’ in glib-or-gtk-build-system.scm is a bit
more subtle, keeping only meaningful share/ directories.
I think qt-build-system.scm should copy that strategy.
Thoughts?

Hi!
Pushed fix as c5fd1b0bd362f8b8578a76a26a65ba5d00d48992.
Maxim Cournoyer <maxim.cournoyer@gmail.com> skribis:

And done in 06eb21856f9535ab62d0becc92b4146e0620654e. Now we can remove
some of these custom phases!
