What do you know about the behavior of the `compiler` flag? When working
with a non-ghc compiler (and not in the snapshot), what exactly is
happening with the version check?
I've been wanting to do this as well... The simplest solution I can imagine
is to escape Stack's desire to handle installation of the compiler, for
example:
```
compiler: ghcjs
setup-info:
ghcjs:
manual: true
path: /usr/bin/ghcjs
```
The main thing is he's trying to remaster the container, so there shouldn't
be any dependence on the host or user that will use the container. Another
related idea is to allow manual specification a location for the snapshot
dir, like:
```
snapshot-override:
- lts-7.0:
/opt/stackage/lts-7/snapshot
```
That would allow easy remastering of the fpco containers by simply running
a stack build for some big lib, at the expense of snapshot sharing on the
host machine. Actually, is there any way that Stack's model could be
extended to allow sub-layering of snapshots? Well, even without it, I think
the option to store your shared snapshot in the container would be very
helpful.
Michael, actually my initial purpose for remastering was to create a yesod
container!
