1.4 Installation Target
Most installations are to a local hard disk. Therefore, it is
necessary for the hard disk controllers to be available to the
installation system. If a special controller, like a RAID
controller, needs an extra kernel module, provide a
kernel module update disk to the installation system.
Other installation targets may be all kinds of block devices that
provide sufficient disk space and speed to run an operating
system. This includes network block devices like
iSCSI or SAN.
It is also possible to install on network file systems that offer
the standard Unix permissions. However, it may be problematic to
boot these, because they must be supported by the
initramfs before the actual system can
start. Such installations are useful if there is a need to start
the same system in different locations or if you intend to use Xen
features like domain migration.
