/etc/localtime to a symlink in the Sysv book.
That would be in LFS Chapter 6 glibc.
It's curious why /etc/localtime needs to be a symlink. If the file is
just opened, the kernel should follow the symlink and do the right
thing. lxde and xfce do not have the problem and neither does xclock.
Something in gnome and, IIRC, plasma, is looking specifically for a
symlink.
The reason for using a cp instead of ln in the glibc instructions is
to keep the time right in the unusual case that /usr is not mounted.
Even if /usr is on a separate partition it is almost always mounted
early (mount is the 7th bootscript) unless there is a problem.
I think I once did something like:
mv /etc/localtime /etc/localtime.file
ln -s localtime.file /etc/localtime
but that's not a good solution for the book.
What do others think? Should we just change LFS from
cp -v /usr/share/zoneinfo/<xxx> /etc/localtime
to
ln -sf /usr/share/zoneinfo/<xxx> /etc/localtime
I believe this is the best solution, and it's consistent with the
systemd book and can remove another difference.
