/var/www/ Chroot partition (ext3)
/var/www/html/ Chroot system
/var/www/html/var/log/apache2 Log partition (ext3)
/var/www/html/var/www/html Webs partition (xfs)
/var/www/html/tmp Temporal dir (tmpfs, optiones: )

/dev/lvm_foobar1/chroot_lv      -> /var/www/ (ext3)
/dev/lvm_foobar2/apachelogs_lv  -> /var/www/html/var/log/apache2 (ext3)
/dev/lvm_foobar3/hosting_lv     -> /var/www/html/var/www/html (xfs)

mkdir -p /var/www/html/var/log/apache2 /var/www/html/var/www/html
mount /dev/lvm_foobar1/chroot_lv /var/www/
mount /dev/lvm_foobar2/apachelogs_lv /var/www/html/var/log/apache2
mount /dev/lvm_foobar3/hosting_lv /var/www/html/var/www/html

3. Clear apache and php instalation
# We never wont install apache or php in non-chroot system, if we have installed, we only have do a backup of confgigurations, uninstall, and check every simbolic link
dpkg -l|egrep --color -i 'apache|php'

4. Prepair chroot enviroment
apt-get install debootstrap libpcre3 libaprutil1 libxml2 mime-support
time debootstrap --arch=amd64 lenny /var/www/html/ ftp://ftp.fr.debian.org/debian/

### Migration to other server ###
Really easy:

Do step 1

And after do a simple rsync:

screen
time rsync -a --progress root@host1:/var/www/ /var/www/

# Install some apache's dependencies
apt-get install debootstrap libpcre3 libaprutil1 libxml2 mime-support

Do step 5
Do step 6
