Cannot enter dm-crypt passphrases
Hey, During system boot, my keyboard doesn't work, and I cannot enter the password for my encrypted disks. I am able to use my keyboard in the installer, bios, and bootloader. I have tried two USB keyboards. Any solution ideas? I have read that the password prompt will timeout. This would work for me because i only have my /home and swap encrypted. My password prompt doesn't timeout. I have also seen suggestions of modifying a mkinitcpio.conf file to include usb keyboard support, but I don't think the debian deployment of dm-crypt uses this file.

You'll have to boot from a cd-rom or using other alternative way, eg, using an installation CD-rom, or some rescue-linux - anything will do that lets you to mount chroot to your existing system. Once there, update busybox package and regenerate initramfs images, by running update-initramfs -k yourkernelversion -u next umount (or just sync) and reboot. You may also use previous busybox version (1.18.x, whatever) which may still be in your /var/cache/apt/archives/ directory. This is all true if you have only one kernel package installed. If there are more than one, you may have good chance to have a working system by booting another kernel, not only the one you updated at the same time with busybox. /mjt -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe.

Dropping wpasupplicant from sparc netboot image
Hello, As we discovered recently, the daily sparc netboot image exceeds 10MB limit imposed by OpenBoot, so it fails to boot. I've poked at it a bit, and it seems that one of the most straightforward ways to make room is to drop wpasupplicant and all its dependencies (libcrypto, crypto kernel modules) which account for significant amount of space on the initrd. AFAIK, sparc does not have any hardware which does wifi natively, and while it's in theory possible to use some usb-wifi dongle to do the installation, I don't remember any reports of anyone doing it. The straightforward way to achieve this goal is to make netcfg not depend on wpasupplicant for sparc (same way as s390 currently does). This will drop wpasupplicant (and, subsequently, installation over wireless support) not only from netboot, but also from all other installation media (like businesscard iso). Let me know if you have any objections, otherwise I'll commit necessary fixes in a couple of days.

Proposal: convert all udebs to xz compression
Hi there,
last week I played around with xz compression and evaluated how d-i
could benefit from it. It turns out that we could go from a total udeb
size (on amd64) of 50 MB to 40 MB just by applying xz -0e compression
instead of the default gzip.
To achieve that you need UNXZ support in busybox, which gives you two
more pages of code (8k) and 700 bytes more in udpkg (both measured on
amd64). So we could neglect this change completely.
I went on and instrumented the unpack calls within d-i by calling GNU
time(1). With gunzip (I made it call the applet instead of relying on
seamless tar support, which isn't yet implemented for xz in busybox) I
get a maximum RSS of 2384 kbytes, assuming that time measures that
correctly. With xz -0 compression I get a maximum RSS of 2608 kbytes.
With the default xz compression of -6 I get a maximum RSS of 11040
kbytes on the largest udebs, as the dictionary is increased. But I only
save less than a megabyte on all udebs, comparing -6e (39484 kbytes) and
-0e (40439 kbytes). So there's absolutely no benefit in activating a
higher compression ratio. For those wondering about the -e bit: packing
udebs gets more costly through this, but its result is more efficient
(43697 kbytes for -0 vs. 40439 kbytes for -0e) while not imposing any
more load onto the unpacker. And we generally don't care about udebs
taking longer to compress given their tinyness and the load being spread
over many package builds anyway.
On my laptop the increased CPU load of unxz was barely noticeable. Some
more calls had a CPU time of 0.00 (i.e. with unxz), but it doesn't
really matter. See [1], [2] and [3] for syslogs with instrumentation.
My patch to udpkg is attached. It's not the best C code, but udpkg is
full of tiny static buffers. I'd appreciate a review.
So my proposal is to switch the udeb compression default in dpkg to xz
for wheezy, when the busybox and udpkg changes have landed. Then most
udebs will get a translation upload anyway, if not they can be binNMUed
to pick up the right compression.
There doesn't seem to be a con at first glance, but if somebody sees
one: please speak up. At least it's untrue that xz will have any
measureable impact when used with -0e, also for embedded systems. If
you're doing a network install it might even be faster, because there
will be less fetching involved. net-retriever might even need less RAM.
Kind regards,
Philipp Kern

Bug#645997: no space on device when installing kernel (lvm+btrfs)

Bug#646306: installation-reports: Corrupted display in wheezy with Asus 1215b
I suspect this may be missing video firmware releated. Screen becomes corrupted soon after encryption password is given when screen mode should switch. I think non-free firmware is required for non-vga modes. I have firmware packages installed in old system and it works fine. Installer didn't warn about it or give option to include non-free repo. I had during install (at separate usb-media) firmware packages firmware-brcm80211_0.33_all.deb (for wlan, installer could use it and wlan worked during installation) and firmware-linux-nonfree_0.33_all.deb (this includes needed Radeon firmwares). Is installer smart enough to copy these packages to installed system? -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
