Merge lp:~sergiusens/snapcraft/mono into lp:~snappy-dev/snapcraft/core

[Sergio Schvezov]

Simple mono project

This is a practice MP that can be turned into a mergeable one.

The current example builds fine, but fails to run due to:
[27737.707903] audit: type=1400 audit(1439434887.243:723): apparmor="DENIED" operation="mknod" profile="mono-hello-google.sideload_run_0.1" name="/dev/shm/mono.2131" pid=2131 comm="hello-google" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000

Not sure if a general apparmor rule is warranted:

  /dev/shm/mono.** rmw, # adding pid is desired.

I'm also not sure how to reuse assembly parts as that is tied to cmd (common.env) and does not allow me to easily -r:[assembly] .. IOW, setting the env (involving knowledge of the other parts) from the plugin would be nice.

A simple hello world works fine.

[Jamie Strandboge (jdstrand)]

If we were to add a rule, we could use this:

  /dev/shm/mono.${pid} rw,

${pid} today just expands to something approaching [0-9]* but the plan is to some day have kernel side variables such that ${pid} would correspond to the running process.

That said, we already have these rules:
/{dev,run}/shm/snaps/@{APP_PKGNAME}/ r,
/{dev,run}/shm/snaps/@{APP_PKGNAME}/** rk,
/{dev,run}/shm/snaps/@{APP_PKGNAME}/@{APP_VERSION}/ r,
/{dev,run}/shm/snaps/@{APP_PKGNAME}/@{APP_VERSION}/** mrwlkix,

Is there an environment variable that can be set in the launcher so that mono will just put the file in /dev/shm/snaps/@{APP_PKGNAME}/@{APP_VERSION}/ ?
