Public bug reported:
https://github.com/CanonicalLtd/netplan/blob/ea47bd4e1c5319b1a624ea61c843ee96e7c128da/src/networkd.c#L208
The separator used to add multiple ARP IP targets for the networkd
renderer is ",".
Unfortunately, networkd doesn't allow that, but rather expects
whitespace:
(in config_parse_arp_ip_target_address():)
[...]
for (;;) {
[...]
r = extract_first_word(&rvalue, &n, NULL, 0);
extract_first_word's third parameter is const char *separators; where
NULL is handled like so (src/basic/extract-word.c:37):
if (!separators)
separators = WHITESPACE;
Finally:
src/basic/string-util.h:#define WHITESPACE " \t\n\r"
So; it doesn't handle commas for the list, just whitespace; so let's
give it whitespace please :)
