[LEDE-DEV] [PATCH 1/2] base-files: also generate configs when current is empty (FS#193)

[Koen Vandeputte]

If a config does not exist, an empty file is created to store the newly
generated one.

- If a powercut happens during generation, it is not stored
- UCI commit does NOT store the generated configs to file on 1st clean
boot

If such a case happens, an empty file exists and it is never
regenerated again, causing some daemons to fail starting
(NTPD, logread, ..)

Fix this by also generating new configs if the current one is empty.
Also fixes this print during boot: "Failed to connect to ubus"
