Debian/Ubuntu patches

Debian/Ubuntu patches

[Jon Ander Hernandez]

Hello,

I post the patches as I promised :-)

- When a new kernel is installed or uninstalled dracut based initramfs
is not automatically created/deleted. Ubuntu's kernel package's post
script executes update-initramfs directly, and the update-initramfs
trigger is never fired.
Another solution is to install a postinst and a postrm script under
/etc/kernel/{postrm.d,prerm.d}.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_kernel_prerm_postinst.diff


- Postinst script can be executed when installing first time dracut,
or when we are upgrading Dracut. Check if it should create a new
initramfs or if it should upgrade it.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_postinst.diff


- Add xsltproc and docbook-xsl as dependencies to the source package,
since they are required for building the man files.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_control.diff


- Create the man files when building the package.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_rules.diff


- rpc.idmapd requires rpc_pipefs to be mounted. On Fedora when the
sunrpc module is loaded, modprobe mounts the rpc_pipefs, while this is
not the case on Debian/Ubuntu.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/nfsroot_mount_rpc_pipefs.diff



I imagine that these should be version specific patches :

- Ubuntu Maverick ships dhclient 3, which doesn't support the "-4" flag.

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_fix_dhclient_3.diff

- Ubuntu's Maverick arping seems to be broken (a least for me).

http://kestrelhpc.svn.sourceforge.net/viewvc/kestrelhpc/Kestrelhpc/Src/dracut/debian_fix_remove_arping.diff

Cheers,

Jon Ander.

Personal comment on the debian/* stuff: It's horribly outdated. Due do 
workload and private reasons I haven't been able to work on them for 
months.

As for these patches, they look sensible. But question: have you tried 
them on debian testing/unstable?

Good one! Please post inline patch.

This is a debian/ubuntu specific fix and should not go in just like 
that. We need a version check to decide if -[46] can be passed or not, 
since newer version of dhclient should be supplied with it.

We need iputils-arping and not the standard arping. Mind checking if you 
are using the correct package?

Ops I'm sorry, I readed the mailing list's guidelines, and I thought
that a patch (inlined) was also considered an attachment.

I have not tried them lately, just in Ubuntu 10.04 and Ubuntu 10.10.

not sure why you want a create at all here, create should be called
by linux-2.6 images not the wrapper script itself.

the changelog vor this change is very confusing,
essentialy you change here from a cdbs source package to a dh one.

ok cool, if you have questions for them please just ask on mailinglist.

the redirect to stderr is needed as linux images might use debconf.

ufff, please look at b5c928d159623f617f872323b7064ebfbf19a269 from
initramfs-tools for a similar switch, you need to fix the control
appropriately:

Please make sure to build this dracut in a chroot
(use sbuild or pbuilder or whatever suits you) in order
to check that it really autobuilds on upload.

Well now I'm also confused... I tested it sometime ago and it failed,
but now it works. May be I did something strange at that time, because
I was doing weird things to discover what was failing till I found the
arping issue. Maybe I should test everything with a different switch.

I've tested dracut without commenting the arping line and yes, I get :

dracut: FATAL: Resolving 192.168.30.1 via ARP on eth0 failed
dracut: Refusing to continue

No root device found

What I'm trying to do is to avoid this error :

dh_installman -pdracut
dracut.8: No such file or directory at /usr/bin/dh_installman line 127.
make: *** [binary-install/dracut] Error 2
dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2


From what I understand (I don't have much experience with debian
packages), dpkg executes "make binary", which doesn't create the man
files. So I found that using dh and overriding the dh_auto_build I
could get it to call "make all" instead.

But you probably will install dracut once you have a linux kernel
installed, so if you do so, the kernel postinst script will create
dracut initramfs for any new kernel image installed, but not for the
current installed one.

yes, but didn't understand your reply and short of time..
this seems like a chicken and egg trouble, please rephrase more coherently.

I'm sorry, I need to improve my English. :-)

I meant that if we ship Dracut with the kernel postinst script
(/etc/kernel/postinst), then the next time a linux image is installed,
that script will be fired and a Dracut based initramfs will be created
for that new kernel.

But when we install Dracut for the first time, there is not any Dracut
based initramfs installed on the system, and Dracut package's postinst
calls actually only call "dracut-update-initramfs -u" which only
updates the initramfs images present in the system (in this case no
one). So after installing Dracut you won't get a Dracut based image
for the kernel you are using, which is not very consistent with the
behaviour of creating the initramfs for any new kernel installed
afterwards.

I understand that is the linux kernel package's mission to call the
kernel postinst scripts under /etc/kernel/postinst, but... I think we
should do something. Maybe make the current linux kernel package call
the /etc/kernel/postinst scripts, or maybe call
dracut-update-initramfs, which was what I was doing in my original
patch... ¿What could be the best solution?

Thanks,

Jon Ander.

no, no this wrong logic.
first of all the linux image depends on the a linux initramfs creator
tool and thus this is installed *before* linux-2.6.

the proposed create seems really wrong, I would nack any postinst
in debian or escalate as serious bug.

if you want hostile takeover that is up to the local admin
and only one command away

Sorry, I didn't think it would be so problematic. I just wanted to
make it "just work" after being installed. After thinking about it, I
realize that I didn't think about a several scenarios such as in an
install using deboostrap.

Thanks a lot for your patience Maximilian,

Thanks for checking. Now i'm confused. Because arping's invocation (sudo 
arping -f -w 60 -I eth0 ...) on my 10.10 works flawless. Is dracut 
"throwing" an error when calling arping or is it the "Resolving $dest 
via ARP on $netif failed" message?
