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
juniper.conf.2.gz       juniper.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

Take care
