/usr/lib/libreoffice/program/soffice is symlinked twice into /usr/bin as libreoffice and soffice

 ** root@agnes ** /usr/bin ** Thu Sep 16 11:09:37
# ls -la *office
lrwxrwxrwx 1 root root 36 Sep 16 10:56 libreoffice -> ../lib/libreoffice/program/soffice
-rwxr-xr-x 1 root root 53 Aug 2 01:31 loffice
lrwxrwxrwx 1 root root 36 Sep 16 11:05 soffice -> ../lib/libreoffice/program/soffice

However, soffice is a shell script which derefs the symlink and then fails to find "../lib"

If one recreates the symlinks with full paths, all is well

 ** root@agnes ** /usr/bin ** Thu Sep 16 11:16:37
# ls -la *office
lrwxrwxrwx 1 root root 36 Sep 16 10:56 libreoffice -> /usr/lib/libreoffice/program/soffice
-rwxr-xr-x 1 root root 53 Aug 2 01:31 loffice
lrwxrwxrwx 1 root root 36 Sep 16 11:05 soffice -> /usr/lib/libreoffice/program/soffice
