Why this page
I use sid since 2011.04.09. I want to keep here all the problems I have encountered.
The problems and their solutions
grub 2
I have installed Wheezy on a partition in case of trouble to be able to use the computer.
So I have got one partition with sid and another with testing. I wanted to change the name of the title in grub.
I had to change /etc/grub.d/10_linux line 65
printf "menuentry 'testing ${title}' ${CLASS} {\n" "${os}" "${version}"
and I had to rename the file from 10_linux to 31 so that it would appear after sid.
Then I had executed update-grub.
