The initramfs generation is broken for file and directory names which contain
colons, spaces and other unusual characters. Print an error and don't try to
continue.
Some tests:
cd linux
make defconfig
echo 'CONFIG_BLK_DEV_INITRD=y' >> .config
echo 'CONFIG_INITRAMFS_ROOT_UID=0' >>.config
echo 'CONFIG_INITRAMFS_ROOT_GID=0' >>.config
echo 'CONFIG_INITRAMFS_COMPRESSION_NONE=y' >>.config
echo 'CONFIG_INITRAMFS_SOURCE="/tmp/bugroot"' >>.config
Problem with colons:
mkdir -p /tmp/bugroot/a:b
make -j4 bzImage # no error
make bzImage # try again, oops
Problem with spaces:
mkdir -p /tmp/bugroot/a\ b
make -j4 bzImage # no error
zcat usr/initramfs_data.cpio.gz | cpio --extract --list # oops, no content
