sudo broken in latest classic

[Alexander Sack]

WORKAROUND (credits to ogra):
  ubuntu@localhost:~$ sudo umount /writable/classic/etc/sudoers
  ubuntu@localhost:~$ sudo mount --bind /etc/sudoers.d /writable/classic/etc/sudoers.d

as reported we got a new sudo ... which didnt upgrade well...
  https://bugs.launchpad.net/snappy/+bug/1564316

now witha fresh classic install i cannot sudo apt-get install anything

(classic)ubuntu@localhost:~$ sudo apt-get update
sudo: no tty present and no askpass program specified

pretty big blocker for anyone who wants to developer for snappy on arm

[Alexander Sack (asac)]

please fix asap... this is blocking me :(

[Oliver Grawert (ogra)]

the actual fix is to make snappy enable-classic actually create a /dev/pts mount:

sudo mount --bind /dev/pts /writable/classic/dev/pts

fixes the issue completely

[Oliver Grawert (ogra)]

according to jamie we should actually do an actual "devpts newinstance,ptmxmode=0666,gid=5 mount" instead of bind mounting /dev/pts from the outside though.

Or anyone who wants to develop anything in classic at all. This happens on amd64 as well.

This is fixed again.
