debootstrapped :: DebootstrapConfig -> FilePath -> Props metatypes -> Chroot Source #
Defines a Chroot at the given location, built with debootstrap.
Properties can be added to configure the Chroot. At a minimum,
add a property such as osDebian
to specify the operating system
to bootstrap.
debootstrapped Debootstrap.BuildD "/srv/chroot/ghc-dev" $ props & osDebian Unstable "amd64" & Apt.installed ["ghc", "haskell-platform"] & ...
bootstrapped :: ChrootBootstrapper b => b -> FilePath -> Props metatypes -> Chroot Source #
Defines a Chroot at the given location, bootstrapped with the specified ChrootBootstrapper.
provisioned :: Chroot -> RevertableProperty (HasInfo + Linux) Linux Source #
Ensures that the chroot exists and is provisioned according to its properties.
Reverting this property removes the chroot. Anything mounted inside it is first unmounted. Note that it does not ensure that any processes that might be running inside the chroot are stopped.
Specification of a chroot. Normally you'll use debootstrapped
or
bootstrapped
to construct a Chroot value.
Chroot :: ChrootBootstrapper b => FilePath -> b -> Host -> Chroot |
class ChrootBootstrapper b where Source #
Class of things that can do initial bootstrapping of an operating System in a chroot.
data Debootstrapped Source #
Use this to bootstrap a chroot with debootstrap.
data ChrootTarball Source #
Use this to bootstrap a chroot by extracting a tarball.
The tarball is expected to contain a root directory (no top-level
directory, also known as a "tarbomb").
It may be optionally compressed with any format tar
knows how to
detect automatically.
noServices :: RevertableProperty UnixLike UnixLike Source #
Adding this property to a chroot prevents daemons and other services from being started, which is often something you want to prevent when building a chroot.
On Debian, this is accomplished by installing a /usr/sbin/policy-rc.d script that does not let any daemons be started by packages that use invoke-rc.d. Reverting the property removes the script.
This property has no effect on non-Debian systems.
inChroot :: Propellor Bool Source #
Check if propellor is currently running within a chroot.
This allows properties to check and avoid performing actions that should not be done in a chroot.
Internal use
provisioned' :: (Property Linux -> Property (HasInfo + Linux)) -> Chroot -> Bool -> RevertableProperty (HasInfo + Linux) Linux Source #
