They do allow the mounting of a USB flash device. Of course, the usual
admonishment about using Juniper USB devices, but you can mount a fat32
formatted USB key:
* Enter the shell as root:
user at switch> start shell user root
root at switch%
* Mount USB to /mnt
root at switch% mount_msdosfs /dev/da1s1 /mnt
* Check the contents in USB disk
root at switch% ls /mnt
juniper.conf.1.gz juniper.conf.3.gz rescue.conf.gz
* Unmount usb disk and then pull it out.
user at switch% umount /mnt
USB keys are cheap too - cheap enough to replace as part of yearly
As usual, YMMV - some USB keys are better than others, and I haven't tried
any larger than 4G.

Heh. Sounds like fun - maybe with a unit once it gets older/off
