Bug#491692: initramfs-tools: udev not copied to ramdisk as hookscript is skipped
Package: initramfs-tools
Version: 0.92e
Severity: important
Hi folks,
i ran into this after trying to install a 2.6.25.10-vanilla using make-kpkg. When I tried to boot the new kernel,
the system hung. It said /scripts/init-premount/udev : 17 : udevd : not found. Well the reason for that was very
simple: udevd was not copied into the kernel image:
Allright here is how one might reprduce it (at least that was how I ran into it):
1. unpack the kernel sources and configure the kernel.
--> After unpacking I did
cd /usr/src/linux-2.6.25.10
zcat /proc/config.gz > .config
make oldeconfig
make menuconfig
2. Create the kernelimage
make-kpkg clean && make-kpkg --initrd --append-to-version=-custom --rootcmd fakeroot \
kernel_image kernel_headers
3. Install the Kernel
dpkg -i /usr/src/linux-image-2.6.25.10-customy_2.6.25.10-customy-10.00.Custom_i386.deb
--> dpkg told me that the ramdisk was created
4.If I reboot now the above described problem happens.
5. To check if udevd was included in the image i unpacked the kernelimage into a directory and tried to find the
udevd binary:
mkdir /home/philipp/Desktop/initrd
cd /home/philipp/Desktop/initrd
zcat /boot/initrd.img-2.6.25.10-customy | cpio -i
find -name '*udev*'
--> which gave me just
./scripts/init-premount/udev
./scripts/init-bottom/udev
Unfortunately i was not able to see what really happend during the creation of the image so i ran:
update-initramfs -utv
which revealed that all the hook scripts were skipped with the message
/usr/share/initramfs-tools/hooks/whatever ignored: not alphanumeric or '_' file
Thus the udev hook script was skipped as well and no udevd-binary was copied.
I worked around this by temporarily changing line 77 of /usr/share/initramfs-tools/scripts/functions
from
*[![:alnum:]_]*
to ___
very very ugly, but however the line, which is in a section which figures out which scripts to exclude from
participation in the ramdisk-image creation process, more or less tells to exclude everything as far as i
interpreted the
glob expression (this *[![:alnum:]_]* string) correctly. Why is that so?
I'd guess it is a bug. Anyhow even if it isn't I would expect the freshly installed initramfs-tools scripts to
create a consistent ramdisk image.
Well that's it basically
Regards
Phil
