[Pkg-kde-extras] Bug#673161: mysql-server-5.1 is available, but fails to start in chroot

[Arnold Metselaar]

Hi,

Being interested in digikam 2.6.0, I have tried building it for Wheezy with my own mini-buildd. 
I have discovered that while mysql-server-5.1 is still available in Wheezy, it cannot be set up
in a schroot environment.
The post installation script of mysql-server-5.1 invokes the init script to start mysqld.
The init script of mysql-server users df to check for a nearly full file system before starting, 
but df fails in a schroot environment, so nothing is started  and apt-get reports an error 
with mysql-server-5.1.

I think the schroot package is to blame here, though it may be argued that the bug should be 
reassigned to some other part of the build system, coreutils (df) or mysql-server-5.1 instead.

Regards,
Arnold
