Preload 0.2 and 0.4 comparison

The installation for 0.2 was from the testing repository and 0.4 from the unstable repository. Both were removed and purged before testing the other.

The bootcharts are obtained after at least 2 reboots.

The configurations used for both cases are:

**default configuration**
script started in /etc/rc2.d/
order: S95preload after S89cron before S99gdm
/etc/preload.conf (modified to adjust to original default)
mapprefix =
exeprefix =

**modified configuration**
script started in /etc/rcS.d
order: S04preload after S04mountdevsubfs.sh before S05bootlogd
/etc/preload.conf contains
mapprefix = /lib; /lib/lsb/; /lib/terminfo/x; /lib/tls; /usr/lib; /usr/lib/gconv; /usr/lib/locale
exeprefix = !/usr/sbin;/usr;!/
