|This type represents an OS image located at osRoot built from a
particular osBaseDistro using a particular osArch. If an
osLocalRepo argument is given, that repository will be copied into
the environment and kept in sync, and lines will be added to
sources.list to point to it.
|osGlobalCacheDir :: FilePath|
|osRoot :: EnvRoot|
|osBaseDistro :: SliceList|
|osReleaseName :: ReleaseName|
|osArch :: Arch|
|osLocalRepoMaster :: Maybe LocalRepository||The associated local repository, where packages we
build inside this image are first uploaded to.
|osSourcePackages :: [SourcePackage]||A copy of osLocalRepo which is inside the changeroot
, osLocalRepoCopy :: Maybe LocalRepo
| Update and return a copy of the local repository
which is inside the changeroot.
|osBinaryPackages :: [BinaryPackage]|
|:: CIO m|
|-> EnvRoot||The location where image is to be built
|-> NamedSliceList||The sources.list
|-> Maybe LocalRepository||The associated local repository, where newly
built packages are stored. This repository is
periodically copied into the build environment
so apt can access the packages in it.
|-> Bool||If true, remove and rebuild the image
|-> SourcesChangedAction||What to do if called with a sources.list that
differs from the previous call (unimplemented)
|-> [String]||Extra packages to treat as essential
|-> [String]||Packages to consider non-essential even if marked essential
|-> [String]||Extra packages to install during the build
|-> AptIOT m OSImage|
|Create or update an OS image in which packages can be built.
|Try to update an existing build environment: run apt-get update
|Use rsync to synchronize the pool of locally built packages from
outside the build environment to the location inside the environment
where apt can see and install the packages.
|To neuter an executable is to replace it with a hard link to
/bin/true in such a way that the operation can be reversed. This
is done in order to make it safe to install files into it when it
isn't live. If this operation fails it is assumed that the
image is damaged, so it is removed.
|Reverse the neuterEnv operation.
|Remove an image. The removeRecursiveSafely function is used to
ensure that any file systems mounted inside the image are unmounted
instead of destroyed.
|Build the dependency relations for the build essential packages.
For this to work the build-essential package must be installed in
