Subject: zic using hardlinks:-(
Hi,
I received the following bug report for GNU libc. Jochen says
that using a hard link doesn't work for his system since /etc and
/usr/share are on different filesystems. zic is from tzcode1997h.
I see three possibilities:
- changing the link call in zic.c to symlink.
- if link fails with error EXDEV (oldpath and newpath are not on the
same filesystem) retry with a symlink.
- leave it the way it is.
Should symbolic links used in general or only for localtime?
Andreas

>Description:
The command "zic -l MET" should set the local time zone by
linking the file "/usr/share/zoneinfo/MET" to
"/etc/localtime". It uses a hard link for this purpose. On
my system this fails, because the directories "/etc" and
"/usr/share/zoneinfo" are located on different disk partitions
on my system. This results in the output
zic: Kann nicht von /usr/share/zoneinfo/MET nach
/etc/localtime linken: Ungltiger Link ber Gertegrenzen hinweg
when I execaute the above command (obviously I use `LANG=de').
>How-To-Repeat:
Find a system, which uses disk partitions as described above,
and execute the command "zic -l MET".
>Fix:
Modify the code in "time/zic.c" to use symlinks (if available)
or to copy the file if the hard link fails.
