A Linux box can run as an iSCSI server.  In fact, ISTR seeing iSCSI as an
option in the Linksys WRT-54G firmware.  That was probably client side
instead of server, because server wouldn't be THAT useful.

If your system supports booting from iSCSI, or you set it up such that it
boots a Linux kernel configured properly to get it's root file-system from
iSCSI.  For example, you could use PXE (which is more common than native
iSCSI) to boot a custom kernel that then knows how to get to it's root
file-system over iSCSI.
