I think we should change /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 would prefer the symlink. 1) the way the book is set /usr is always mounted The /usr partition to be mounted or not is more an issue related with disk partitioning and brand new system installation. 2) When you copy zoneinfo/something to /etc as "localtime", you are losing what is the current timezone setup. If you use symlink the time-zone is displayed (lets say /usr/share/zoneinfo/EST5EDT) if (as admin) you want the change system time zone, you know, first glance, where to look to set your own time-zone. -- seen "Linux from scratch" and looking for ISO files www.osukiss.org
