Does it boot from usb?
http://tanael.org/alpine/v1.1/usbdrive/

Does it boot from floppy? there are floppy images on the iso that will
load the kernel from floppy, cdrom drivers and then load the rest from
cdrom.

They are slow. For fast boots, i'd try to make initng work. (but its
big)

Might be that its fast enough for you if you dont need the
coldplugging.

It means that is pulls in runtime packages during boot to a tmpfs. All
runtimes (binary pacakges) are loaded into ram during boot instead of
the classical livecd approch where you mount a squashfs or uninonfs on a
cdrom.

The drawback is long boot times (you need to install all your packages
every time you boot)

The benefit is you prevent delays caused by cdrom spinning up
(everything is in ram so responsetimes should even be faster than from
disk) and you can do (security) updates without rebooting.

Its designed for routers, firewalls, small servers without harddisk.
