[Fedora-livecd-list] PowerPC support.

At http://git.infradead.org/?p=users/dwmw2/livecd-ppc.git (git://git.infradead.org/~dwmw2/livecd-ppc.git) there's a set of patches which first introduces a little abstraction for the arch-specific configureBootloader() and createIso() functions, then implements the PPC version. 1. Allow mayflower path to be specified, to run from git tree 2, Remove syslinux from package lists; add it dynamically instead. 3. Move x86-specific functions (createIso, configureBootloader) into subclass 4. Only create isolinux/ directory in x86-specific configureBootloader() 5. Add PowerPC support, add pata_mpc52xx module to mayflower.conf The full patch is as follows... diff --git a/config/livecd-fedora-desktop.ks b/config/livecd-fedora-desktop.ks index 1ee6fba..780e201 100644 --- a/config/livecd-fedora-desktop.ks +++ b/config/livecd-fedora-desktop.ks @@ -23,7 +23,6 @@ services --enabled=NetworkManager,dhcdbd --disabled=network,sshd @dial-up @hardware-support @printing -syslinux kernel scim* diff --git a/config/livecd-fedora-kde.ks b/config/livecd-fedora-kde.ks index 20413b1..9aeceed 100644 --- a/config/livecd-fedora-kde.ks +++ b/config/livecd-fedora-kde.ks @@ -23,7 +23,6 @@ kernel dejavu-lgc-fonts setroubleshoot smolt -syslinux system-config-display xorg-x11-drivers diff --git a/config/livecd-fedora-minimal.ks b/config/livecd-fedora-minimal.ks index e8065b6..db52912 100644 --- a/config/livecd-fedora-minimal.ks +++ b/config/livecd-fedora-minimal.ks @@ -17,7 +17,6 @@ repo --name=a-extras-dev --baseurl=http://download.fedora.redhat.com/pub/fedora/ %packages bash kernel -syslinux passwd policycoreutils chkconfig diff --git a/config/livedvd-fedora-kde.ks b/config/livedvd-fedora-kde.ks index 1ed2f57..71aa122 100644 --- a/config/livedvd-fedora-kde.ks +++ b/config/livedvd-fedora-kde.ks @@ -23,7 +23,6 @@ kernel dejavu-lgc-fonts setroubleshoot smolt -syslinux system-config-display xorg-x11-drivers diff --git a/creator/livecd-creator b/creator/livecd-creator index a526b07..755e659 100755 --- a/creator/livecd-creator +++ b/creator/livecd-creator @@ -27,6 +27,8 @@ import traceback import subprocess import shutil import yum +import rpmUtils.arch +import rhpl import pykickstart.parser import pykickstart.version @@ -277,6 +279,178 @@ class LiveCDYum(yum.YumBase): cb.filelog = False return self.runTransaction(cb) +class InstallationArchPPC: + def __init__(self): + # For now we need anaconda-runtime, for bits like ofboot.b and mapping files. + # We could generate those ourselves though... + self.bootldr_package = ("yaboot","anaconda-runtime") + + def createIso(self, target): + """write out the live CD ISO""" + subprocess.call(["/usr/bin/mkisofs", "-o", "%s.iso" %(target.fs_label,), + "-hfs", "-hfs-bless", "%s/out/ppc/mac" %(target.build_dir), + "-hfs-volid", "%s" %(target.fs_label,), "-part", + "-map", "/usr/lib/anaconda-runtime/boot/mapping", + "-J", "-r", "-hide-rr-moved", "-no-desktop", + "-V", "%s" %(target.fs_label,), "%s/out" %(target.build_dir)]) + + def configureBootloader(self, target): + """configure the boot loader""" + + # Copy yaboot and ofboot.b in to mac directory + os.makedirs(target.build_dir + "/out/ppc/mac") + shutil.copyfile("%s/install_root/usr/lib/anaconda-runtime/boot/ofboot.b" %(target.build_dir), + "%s/out/ppc/mac/ofboot.b" %(target.build_dir,)) + shutil.copyfile("%s/install_root/usr/lib/yaboot/yaboot" %(target.build_dir), + "%s/out/ppc/mac/yaboot" %(target.build_dir,)) + + # Copy yaboot and ofboot.b in to mac directory + os.makedirs(target.build_dir + "/out/ppc/chrp") + shutil.copyfile("%s/install_root/usr/lib/anaconda-runtime/boot/bootinfo.txt" %(target.build_dir), + "%s/out/ppc/bootinfo.txt" %(target.build_dir,)) + shutil.copyfile("%s/install_root/usr/lib/yaboot/yaboot" %(target.build_dir), + "%s/out/ppc/chrp/yaboot" %(target.build_dir,)) + subprocess.call(["/usr/sbin/addnote", "%s/out/ppc/chrp/yaboot" %(target.build_dir,)]) + + os.makedirs(target.build_dir + "/out/ppc/ppc32") + shutil.copyfile("%s/install_root/boot/vmlinuz-%s" + %(target.build_dir, target.get_kernel_version()), + "%s/out/ppc/ppc32/vmlinuz" %(target.build_dir,)) + shutil.copyfile("%s/install_root/boot/livecd-initramfs.img" + %(target.build_dir,), + "%s/out/ppc/ppc32/initrd.img" %(target.build_dir,)) + os.unlink("%s/install_root/boot/livecd-initramfs.img" + %(target.build_dir,)) + + os.makedirs(target.build_dir + "/out/ppc/ppc64") + # FIXME: Need 64-bit kernel and initrd + + cfg32 = """ +init-message = "Welcome to the Fedora %(label)s LiveCD" +timeout=6000 + +""" %{"label": target.fs_label} + + stanzas = [("linux", "Run from image", ""), + ("runfromram", "Run from RAM - requires 1 GiB+", "live_ram")] + if os.path.exists("%s/install_root/usr/lib/anaconda-runtime/checkisomd5" %(target.build_dir,)): + stanzas.append( ("check", "Verify and run from image", "check") ) + + for (short, long, extra) in stanzas: + cfg32 += """ + +image=/ppc/ppc32/vmlinuz + label=%(short)s + initrd=/ppc/ppc32/initrd.img + read-only + append="ro quiet root=CDLABEL=%(label)s rootfstype=iso9660 %(extra)s" +""" %{"label": target.fs_label, + "short": short, "long": long, "extra": extra} + + cfgf = open("%s/out/ppc/ppc32/yaboot.conf" %(target.build_dir,), "w") + cfgf.write(cfg32) + cfgf.close() + os.makedirs(target.build_dir + "/out/etc") + cfgf = open("%s/out/etc/yaboot.conf" %(target.build_dir,), "w") + cfgf.write(cfg32) + cfgf.close() + + # FIXME.
