Already the third time this happens to me: An update is available for the mysql server and I just "apt-get upgrade". The upgrade process gets totally stuck at the following task:

mysql stop/waiting
The process that got again stuck in some eternal loop (or whatever) is an egrep replacement of some textfile:
egrep -qi -r ^[^#]*ndb.connectstring|^[:space:]*\[[:space:]*ndb_mgmd /etc/mysql/

• Insert pages with interleave: pdftk A=input_odd_pages.pdf B=input_even_pages.pdf shuffle A B output collated.pdf(from the pdftk package)
• Split an A2-sized PDF into two A3 pages for printing (no overlap): pdfposter -m A3 -p A2 Periodic-Table_A2.pdf Periodic-Table_2xA3.pdf
• Split an arbitrary-sized PDF into A3 pages for printing at 100% size (= 1), no overlap: pdfposter -m A3 -s1 Poster.pdf Poster_split_to_A3.pdf

On the receiving machine (disk sda MUST be unmounted, e.g. by booting from a live CD or USB stick):
netcat -l -p 4778 | dd of=/dev/sda

On the sending machine (disk sdb MUST be unmounted, e.g. by booting from a live CD or USB stick):
dd if=/dev/sdb | netcat 192.168.0.4 4778
