Description Vincent Cautaerts 2000-01-20 21:14:36 UTC
I moved /usr/X11R6 to a partition /More, making it then
I created a symlink (ln -s /More/usr/X11R6 /usr/X11R6),
but X didn't work after that:

there are links, like
/usr/X11R6/lib/X11/fs -> ../../../../etc/X11/fs/
which don't work in my case, since, because of the symlink
"/usr/X11R6/../.." is "/More/" and not "/".

The solution is simple: make a fully qualified symlink
/usr/X11R6/lib/X11/fs -> /etc/X11/fs

I can't see the utility to have a symlink descending up to
root with lots of "../../../../" (except that it may facilitate
making the packages).

I understand that sometimes one may want to use a link like
"../bin/xx" inside a package (to make a relocatable package), but for
links that anyway go down to "/", I can't see the utility of this.

This problem will most probably also occur when installing, if somebody
decide to create a partition to hold for example both "/usr/" and "/lib",
creating this partition "/SomeName", with in it "/SomeName/usr" and
"/SomeName/lib", and symlinks
"/lib -> /SomeName/lib", "/usr -> /SomeName/usr".

Anyway, thanks for the great work.

these relative symbolic links are very useful when you have to boot in rescue
mode and mount your tree under say /mnt.  Absolute symlinks are actually worse
in many instances.

You can't win.
