Every few hours, a server gets stuck in a state where certain users receive ENOENT from getcwd(), resulting in errors like

shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

Sometimes the problem goes away on its own, but usually the server needs to be rebooted.

I attempted to debug this with upstream on ​2013-06-11 and ​2013-06-16. Using crash, I found that we’re ending up with two dentries referring to the same directory inode, which is ​bad. We’re all confused.

scripts-pony/scripts/templates/master.mak has a very inefficient Konami code detection easter egg that appends all keystrokes to a JavaScript? array. It should be rewritten to use the obvious 11-state Knuth–Morris–Pratt FSM.

This now also affects XVM, who copied this code.

Now that OpenAFS is fixed, none of our servers should need allow_weak_crypto. We should disable it everywhere.

We may need to contact users that use kinit on scripts, which at the time of this writing, is likely to be approximated by
