usb disk support

[tehn]

to get it set up:

sudo apt-get install usbmount

then modify /etc/usbmount/usbmount.conf

MOUNTOPTIONS="sync,noexec,nodev,noatime,nodiratime"
FS_MOUNTOPTIONS="gid=we,pid=we"
VERBOSE=no

and modify /lib/systemd/system/systemd-udevd.service

this should make a FAT formatted disk enumerate at /media/usb0 when plugged in

the mystery now--- UI wise--- is what makes sense for sync'ing. previously (and perhaps most sensibly) we have to options:

• DISK >>> NORNS
• NORNS >>> DISK

we only operate on the dust folder.

after trying a variety of rsync options i'm still not sure what makes sense--- ie, only copy updated/new files.

for what it's worth, disk copying is extremely slow.

i'm almost compelled to suggest that if people want fast copying, use a usb-ethernet cable (which might mean using two of them, if going to another computer w/o an ethernet port.)
