@EIPI : keeping terminal open isn't necessary ! daemons are running, because it's daemon, you can close chrooted terminal
moreover, i installed "bluefish" in order to edit web html & php & css pages,...

i made a script in debian :
#nano /usr/local/sbin/lamp_start.sh :
_______________
#!/bin/bash
/etc/init.d/apache2 start
/etc/init.d/mysql start
_______________
then
#chmod u+x /usr/local/sbin/lamp_start.sh

back in Maemo,
you can put in /etc/init.d/rcS or something like this, before exit 0 at the very end of the file :
________________
...

sudo debian lamp_start.sh

exit 0
