Question: i am working on [LFS](http://www.linuxfromscratch.org/lfs/view/stable/chapter04/creatingtoolsdir.html), and getting this error creating symbolic links. i checked this [link](https://askubuntu.com/questions/524606/creating-a-symbolic-link-to-a-directory) but no help, also googled but nothing works. 

```
# ln -sv $LFS/tools /
‘/tools’ -> ‘/mnt/lfs/tools’

```

in root directory, i see a file *tools*, with link symbol on it. double clicking throws an error *"the link cannot be used because its target /mnt/tools does not exist"*

also checked env variable 

```
# echo $LFS
/mnt/lfs

```

any help would be awesome.

thanks

Answer: 
Have you tried the `pdfposter` package? From [the project's website](http://pythonhosted.org/pdftools.pdfposter/): *"Pdfposter can be used to create a large poster by building it from multiple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size."*

I tried a quick example from the man page: `pdfposter -mA3 -pA0 askUbuntu.pdf printer-pages.pdf` with your sample file (which I converted to PDF in Inkscape), and it seems to work : 6 A3 pages that need to be set in a 2×3 grid.
You can save as the image as pdf from inkscape directly using the highest 
resolution (dpi), say 600, of the printer you plan to use for printing.

Afterwards, you can use imagemagick (command convert) to crop the upper and lower parts of the image independently into two different pdf files. For instance (typed on a terminal): 

```
convert askUbuntu.pdf -crop 100%x50% +repage askUbuntuSplit.pdf

```

You can then split it into individual pdf files using:

```
pdftk filename.pdf burst

```

I presume imagemagick and pdftk are already installed.
