Dump the current layout, for example dvorak

mkdir -p /etc/kbd/
dumpkeys > /etc/kbd/dvorak-ctrlcaps.map

Change the 29 and 58 entries

keycode  29 = Control         
keycode  58 = Caps_Lock

Test it

loadkeys /etc/kbd/dvorak-ctrlcaps.map

Make it persistent in /etc/vconsole.conf

KEYMAP=/etc/kbd/dvorak-ctrlcaps.map
