USB booting :: 'dsl' or 'dsl frugal'

Hello, the syslinux.cfg of bootusb-0.8.img has the option 'frugal' for each entry.

The syslinux.cfg of boot-0.8.img doesn't have the option 'frugal'.

For a normal use with a USB key, which is better? Apparently, my USB DSL works equal, I don't know the differences.

The boot-0.8.img is "the boot floppy" for use with a cdrom.
It does not have room on the floppy for all the drivers that would be available when booting from the cdrom.

The bootusb-0.8.img is "the boot floppy" for usb devices, no cdrom, since it is not a good idea to do a full install of DSL onto a usb device, it is assumed that it is a frugal install, ie, a compressed image install. Frugal specifically supressed the "wait for cdrom to eject message that would only apply to cdroms.

Ok, I now understand.

How can I apply updates to the frugal installation
