Comment 14 for bug 297428

Okay, wow, upstream closed that without delay.

So it seems upstream feels that these files are NOT intended to be end-user configurable files, and have rejected the bug report. Given that, I think I'm just going to drop the bits from the README.Debian entirely. The approach seems a bit hackish anyway, and as you point out, prone to get overwritten on upgrade.

What I might suggest, if you still would like an ability to do this, is that you file a wishlist bug upstream to support keyboard layout customizations, so we can get proper support added for it.
