I have written a patch to debootstrap which implements support for
acquiring .debs via a tarball instead of the network.
the way this works is you give debootstrap a mirror of
tar://some/where/basedebs.tgz instead of a normal file:// or http://
URL. debootstrap will extract the tarball in $TARGET/var and then
proceed as if it just downloaded all the packages via the network.
the tarball must contain cache/apt/archives/ and lib/apt/lists (or
state/apt/lists).
i wrote a basic script to build a basedebs.tgz its included in this
patch. for this script to work i needed a --download-only option to
debootstrap, so i added that as well.
Note that this does not attempt to solve the root filesystem base
tarball that some people want for setting up NFS roots. i don't think
that needs to be supported in either debootstrap or the
boot-floppies. rather i think someone should make a debian package
say nfsroot-pmac which in its build process runs debootstrap and then
tars up the result. (or something similar).
this tarball acquisition method for debootstrap would simply be to
solve the ppp problem we have now, without saying `ffs! buy a CD!
foad!'
all b-f would have to do is add a single extra option: `tarball on
mounted filesystem' where the user would pick a basedebs.tgz on a
mounted filesystem (hard disk partition most likely) and dbootstrap
would just run debootstrap using tar://instmnt/basedebs.tgz as its
mirror. easy.
i post this here just to get comments on the implementation. if we
decide that supporting a basedebs.tgz in b-f is useful i think this is
the least problematic way to go about it. i see no reason for b-f to
support a root filesystem tarball since the only reason anyone seems
to want one is setting up NFS roots for different archetecures, that
task does not use b-f, so these can be built/kept somewhere else.
