desktop LTS 12.04/.2 broken cifs support on install

While initrd.lz includes cifs.ko the modules des_generic.ko and md4.ko are missing.

CIFS is very handy when PXE booting Ubuntu LTS Desktop live from Windows OSs as Serva does it here.
http://vercot.com/~serva/an/NonWindowsPXE3.html

The inclusion of des_generic.ko and md4.ko within initrd.lz would avoid the need of loading manually made complementary initrd files.

I hope you guys can add these 2 files for 12.04.3 considering this is an LTS.
Thanks

The bug is confirmed and it is displayed on install when CIFS services are needed; The install aborts.
The solution has been tested and is included in the first post.

Not a kernel problem. The crypto-modules udeb contains both des_generic and md4.

Could someone test if ubuntu-12.04.3 Desktop PXE booting works when .iso images are on CIFS file server?

@mantas

ubuntu-12.04.3-desktop-amd64.iso
ubuntu-12.04.3-desktop-i386.iso

des_generic.ko and md4.ko are still not included within initrd

PXE/CIFS still broken

[patpat (masottaus)]

There's even a new annoyance;

ubuntu-12.04.3-desktop-amd64.iso

has a renamed kernel; the old

\casper\vmlinuz

is now called

\casper\vmlinuz.efi

forcing to edit all the working scripts and menus "only" for the 12.04.3 amd64 version...

[latimerio (fomember)]

with windows cifs not supporting vers=1.0 anymore it is crucial that the crypto kernel modules are included in the initial ram images.
Otherwise it is not possible to mount any cifs volumes from the ram image.

This bug is still open with Ubuntu 18.04.1 LTS.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
