# Functions library :: for Linux Live scripts 5.x.y
# Author: Tomas M. <http://www.linux-live.org>
#
# modified by Urs Beyerle, PSI
# - to allow LiveCD mounted over nfs
# - add scsi_mod, sd_mod for usb-storage module
# - only with boot option "automount", all devices in fstab are rw automounted
# - remove detect of CD and Floppy (done by fstab-sync)
# - add sr_mod (USB CDROM support)
# - add SATA to modprobe_usb_modules -> modprobe_usb_sata_modules
# - add fscache (for SL5) 
# - add ide-cd, sr_mod, cdrom (for SL5 cdrom support)
# - add aufs (unionfs replacement)
# - to allow LiveCD mounted over NFS (for diskless client)
# - add functions get_dhcp_lease() and load_network_modules()
# - add ata_piix to modprobe_usb_sata_modules
