Subject: base-files: fix zoneinfo support
X-Git-Tag: v21.02.0-rc4~57
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3047df231743969ec2b4641d531e888b8c7f30e0;p=openwrt%2Fopenwrt.git

base-files: fix zoneinfo support

The system init script currently sets /tmp/localinfo when zoneinfo is
populated. However, zoneinfo has spaces in it whereas the actual files
have _ instead of spaces. This made the if condition never return true.

Example failure when removing the if condition:

/tmp/localtime -> /usr/share/zoneinfo/America/Los Angeles

This file does not exist. America/Los_Angeles does.

Ran through shfmt -w -ci -bn -sr -s
