symlinking /modules to '/lib/modules' inside the runtime image is fine,
but since we're operating outside the runtime image, the absolute
symlink will point to the host's /lib/modules, which can cause us to
delete kernel modules. Yikes.
Instead:
1) use /lib/modules rather than the symlink, and
2) use a relative symlink, just to be safe.
This lets us easily do whitelisting instead of blacklisting during
runtime cleanup. For example:
removefrom xfsprogs --allbut /sbin/* /usr/sbin/xfs_admin
would remove everything from the xfsprogs package except files in /sbin
and /usr/sbin/xfs_admin.
A few things in runtime-cleanup have been converted to use --allbut. The
only difference in the created runtime image is that we're deleting
/usr/share/kde4 from fedora-logos.
- use libdir in GConf2
- delete redundant removals of /usr/share/gnome/*
- remove systemd units for nfs-utils
- remove all of notification-daemon rather than piece-by-piece
- don't try to delete non-existent libldif from openldap
- /usr/sbin/xfs_bmapd is actually /usr/sbin/xfs_bmap
- remove /etc/* from yum rather than etc/*
also make sure we clean a bunch more unneeded services, but don't bother
deleting target files that would just be ignored anyway.
also also, delete everything in /etc/systemd/system/default.target.wants
so that we don't get readahead stuff in anaconda.
Add commentary for a bunch of the removepkg lines, and drop a bunch of
things that were in the list that weren't being installed anyway. Also
drop some redundant removepkg lines about chkconfig.
removing packages sadly doesn't run their %post scripts, so a lot of
broken links are left around for systemd units and/or sysvinit scripts.
So, after other cleanup, remove any broken links in /etc, /usr, or /lib.
Clean a bunch of things that we don't need to removepkg:
- packages with no files (*-filesystem, basesystem)
- packages that only contain files that will be deleted anyway
(e.g. *-fonts-common - only contains files in /usr/share/doc)
- packages that aren't being installed or no longer exist
(hal-libs, clutter, mutter, libXv, redhat-menus, etc)
- consolidate perl lines to just: removepkg perl*
To build F15 images we need to remove systemd and set up loader as init
(see runtime-cleanup and runtime-postinstall).
We also need to add a hack to dracut so loader won't freak out when it
gets started by anaconda - see the file we're adding to the initramfs in
treebuilder.py.
(There's also an extra bonus hack for working around a bug in dracut if
/proc/cmdline is empty - SEE IF YOU CAN SPOT IT!!!)
Removing the 'module' whitelist added ~50M of kernel modules. Yuck.
This commit adds a kmod blacklist, removing ~34MB of kernel modules.
Yes, that's a ~16MB increase, but we're also including a whole mess of
stuff that was getting left out before: missing ISDN drivers, wireless
drivers, net bonding drivers, infiniband drivers, etc.
