one can see that loadkmap does not handle the value K_ALLOCATED == 638
correctly. when we dump and load the kmap multiple times, the number of
errors increase.
if we begin with
loadkeys /share/keymaps/i386/qwertz/de_CH-latin1.map.gz (loadkeys from
kbd-1.15.3)
dumpkmap > test.kmap
loadkmap < test.kmap
warning: failed to set key slot 6,0 to 638, reason: Invalid argument
dumpkmap > test.kmap
loadkmap < test.kmap
warning: failed to set key slot 6,0 to 638, reason: Invalid argument
warning: failed to set key slot 9,0 to 638, reason: Invalid argument
warning: failed to set key slot 10,0 to 638, reason: Invalid argument
unfortunately both kernel source code and kbd source is undocumented
when they deal with K_ALLOCATED and K_NOSUCHMAP, so i am uncertain on
how to fix it.
