cp -a is used in the makefile. The -a means no dereference and preserve
links and other attributes. This should not be a problem if you have
the same user.

You can try to change "cp -a" by "cp -dPR". Maybe this will help with
fakeroot.

I didn't understand your point.

Among the keymaps, there are symlinks to change the keymap name.
Previously, when compressing keymaps, symlinks were dereferenced and
a copy of the keymap appeared instead of the symlink.

I don't want to create symlinks in Makefile at the time of install. This
is really hard to maintain.
