Subject: [PATCH] dracut-functions.sh:print_vars() fix for values with spaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

for a variable with spaces, e.g.:
EXT_KEYMAPS='backspace keypad euro2'

The following would occur:
print_vars: eval printf -v _value %s '$EXT_KEYMAPS'
print_vars: printf -v _value %s backspace keypad euro2
print_vars: [[ -n backspacekeypadeuro2 ]]
print_vars: printf '%s=\"%s\"\n' EXT_KEYMAPS backspacekeypadeuro2

Thanks to Sebastian Köln for the fix!
