This patch is used on openSUSE 12.2 or newer. Nowadays,
|
|
/etc/localtime is by default a symbolic link to a zone
|
|
file in /usr/share/zoneinfo.
|
|
|
|
By default, zic tries the following approaches to create
|
|
/etc/localtime:
|
|
|
|
1. Hard link
|
|
2. Symbolic link
|
|
3. File copy
|
|
|
|
This patch changes the logic slightly: keep using symbolic
|
|
links if /etc/localtime is already one. If it isn't, use
|
|
the default order as listed above.
