Running parallel commands that require a sudo password borks input

[purpleidea]

Running a command like:

vagrant destroy host

will cause sudo to prompt if it's necessary to clear an NFS mount for example. It's annoying, but not impossible to enter your password.

Running a parallel command such as:

vagrant destroy host1 host2 ...

Causes multiple sudo prompts to happen at the same time (or near the same time). Attempts to enter a password were not successful. I had to ^c multiple times, and then 'reset' the terminal.

Cheers,

This is related to: #2642 and #2643

Note: the only workaround I found was to run the command with the --no-parallel flag, unfortunately this disables the parallel goodness.

@purpleidea As a workaround, would it help to warm up the sudo cache just before?

sudo true; vagrant destroy host1 host2 ...

[purpleidea]

@tmatilai indeed I do, actually, however if the command runs longer than the sudo timeout, it's not possible. Or more specifically, if enough machines are getting deployed/changed, eventually you'll reach timeout and bork the whole lot.

Good bug. Thanks.

@mitchellh no problem. I've been vagrant-ing a lot lately ;) I quite like it so far, except for the occasional bug of course...
cheers!
