Subject: dracut-functions.sh:print_vars() fix for values with spaces
X-Git-Tag: 038~33
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7a94a4326f0641396125acb2b444b562224457a1;p=thirdparty%2Fdracut.git

dracut-functions.sh:print_vars() fix for values with spaces

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!
