I wanted to mention this in case anyone else was spending cycles on it,
since after spending a bit of time on it with rbasch and the zephyrverse
earlier we mostly have an answer, but it's not checked in yet:
- share-mounting /media makes usb device automounting work
- bind-mounting /dev/shm and /dev/pts makes matlab and mathematica work
(but recursively bind-mounting /dev is bad because unmounting becomes
problematic)
A replacement athena-login-snapshot that fixes these is in
/afs/dev/user/amb/tmp, and will be checked in as soon as I'm sure that it
both works and that the initial operations on /media are idempotent and
don't need to be wrapped. (Or moved elsewhere, but I like keeping them
with the other bind-mounting stuff for clarity's sake.)
I like the unionfs idea a lot, but implementing it now to replace the LVM
snapshot approach seems a touch ambitious.
