First, we just install the kernel module and keep track, what we
installed. At the very end, call modprobe and modinfo for firmwares to
resolve all kernel module dependencies. This speeds up image creation,
because we can call modprobe and modinfo with many modules.
cp will use COW data copy most of the time. So, it's even better than
hardlink, because we don't have to care about hardlinks, when modifying
files in post.
Hi Jon,
here's the diff which works for me. The quotation marks around $@ do
not work for me. Instead of "$@" I must to use $_dir/$@ (or
"$_dir"/$@) but no quotation marks around $@. Could you please review
my patch.
This patch adds check of kernel module existance and
propagate errors to upper callers.
In case of break other callers of instmods(), this patch
adds an option '-c' to it, only when "-c" is specified
we fail, otherwise, errors are ignored.

Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup

Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:
inst_libdir_file "libdevmapper-event-lvm*.so"
If symlink is yet alone in target directory, inst_symlink will fail to
create it. This is how to reproduce the bug:
# mkdir /tmp/test
# ln -s /bin/cp /tmp/test/cp
# ./dracut -l -f -H /tmp/test.img -I /tmp/test/cp
Result:
[...]
I: *** Including modules done ***
ln: failed to create symbolic link
`/var/tmp/initramfs.Z5isVu//tmp/test/cp': No such file or directory
ln: failed to create symbolic link
`/var/tmp/initramfs.Z5isVu//tmp/test/cp': No such file or directory
I: Wrote /tmp/test.img:
[...]
Following patch creates directory for the symlink if it doesn't exist.
The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).
The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
first check for omit, then mark the kernel module as seen
when we temporarily omit_drivers, we don't want to mark them as seen.
example: nfs.ko module in kernel-modules, but the nfs module
should be able to load it later on.
