Always use the unstable version of live-build in your host build machine. At
the time of writing this means version 3.0~a67-1. You can grab the one-off .deb
here:
http://packages.debian.org/sid/live-build
### Errors when building flat ("plain") filesystem images
NOTE: these problems should have been fixed by removing the rootfs stage from
caching?
When building a chroot-filesystem=none image, if you encounter:
cp: cannot create regular file `binary/live/filesystem.packages': No such file or directory
You will need to:
mkdir binary/live
rm -rf cache/binary_rootfs
If you don't run the second line as well, you will get the error:
cp: cannot stat `cache/binary_rootfs/filesystem.*': No such file or directory
### Missing symlinked files
When building hdd images, often targetting the FAT32 filesystem, all symlinks
get removed from the binary image. If you are trying to create a "plainroot"
image using ext3 or any unix-style filesystem, this is a big problem. To
disable this step, edit /usr/lib/live/build/binary_includes on the host build
system, and around line 57 comment out the line:
find binary -type l | xargs rm -f
If you get a boot error like:
Kernel panic - not syncing: Attempted to kill init!
Then init may be unable to link to necessary library (like lib/ld-linux.so.3),
because of some badness in the binary build system. If you can't do the above
hack editing the symlink deletion out, you could do:
lb clean --binary
lb config
lb binary_chroot
lb binary_rootfs
lb binary_hdd
### mksquashfs Segfaults in qemu
mksquashfs always segfaults when run inside of qemu. Perhaps due to large
memory requirements of mksquashfs?
One hack workaround is to install the squashfs-tools in the host build system,
then edit the file /usr/lib/live/build/binary_rootfs and around line 377
comment out:
Chroot chroot "mksquashfs chroot filesystem.squashfs ${MKSQUASHFS_OPTIONS}"
and insert:
cd chroot
mksquashfs chroot filesystem.squashfs ${MKSQUASHFS_OPTIONS}
cd ..
Previously tried adding the following mksquashfs arguments, but they didn't fix
the problem:
export MKSQUASHFS_OPTIONS="-processors 1 -read-queue 8 -write-queue 16 -fragment-queue 8"
### squashfs image too small
The Calculate_partition_size function seems to be too optimistic; sometimes
images will not fit in the generated partitions.
Add the following below line 132 of /usr/lib/live/build/binary_hdd in your host
environment to add an extra 50MB to the partition size (probably way more than
necessary):
DU_DIM="$(echo 50 + $DU_DIM | bc)"
### Adding packages to config/packages.chroot
When a new package is added to config/packages.chroot, the entire build
environment must be refreshed (lb clean --purge).
Otherwise you will get an error like:
E: Unable to locate package <packagename>
