Re: [Libguestfs] Rethinking appliance building
To make this even more explicit:
(1) There has to be a way to detect that the package manager should
be used, eg. by looking for /etc/arch-release
RPM: check for existence of /etc/redhat-release
Debian: check for existence of /etc/debian_version
(2) There must be a way to take a list of package names, and fully
resolve all dependencies (recursively as necessary) to get a complete
list of packages that must be installed to bootstrap.
RPM: [lots of Yum API magic]
Debian: apt-cache depends --recurse -i <list of package names>
(3) Must be a way to download a package.
RPM: yumdownloader <name of package>
Debian: aptitude download <name of package>
(4) Must be able to list out the files in a downloaded package.
RPM: rpm -qlp foo.rpm
Debian: dpkg-deb -c foo.deb
(5) Must be able to extract a single file from a downloaded package.
RPM: rpm2cpio foo.rpm | cpio -id
Debian: dpkg-deb --fsys-tarfile foo.deb | tar xf -
So it's almost enough for you to tell me the equivalent of those
commands for pacman, although of course I'd prefer a patch to
febootstrap!
