define Package/debootstrap/description
|
||||
debootstrap is used to create a Debian base system from scratch,
|
||||
without requiring the availability of dpkg or apt. It does this by
|
||||
downloading .deb files from a mirror site, and carefully unpacking them
|
||||
into a directory which can eventually be chrooted into.
