Bug#579336: update-initramfs: recognize (and ignore?) moduleless/ramdiskless kernels.
Package: initramfs-tools
Version: 0.94.4
Severity: wishlist
Following the kernel handbook, I built a mainline kernel using "make
deb-pkg". This kernel is configured without modules or initrd
support. On installing it with dpkg -i, I got this:
$ sudo dpkg -i ../linux-image-2.6.34-rc5_twb1_amd64.deb
Preparing to replace linux-image-2.6.34-rc5 twb1 (using .../linux-image-2.6.34-rc5_twb1_amd64.deb) ...
Unpacking replacement linux-image-2.6.34-rc5 ...
Setting up linux-image-2.6.34-rc5 (twb1) ...

It would be better if initramfs-tools 1) wasn't run in the first
place; or 2) gave a clearer error message, such as:
update-initramfs: Generating /boot/initrd.img-2.6.34-rc5
WARNING: CONFIG_MODULES=n in 2.6.34-rc5, a ramdisk is likely useless.
FATAL: CONFIG_BLK_DEV_INITRD=n in 2.6.34-rc5, a ramdisk is useless.
In particular, this current warning is unintelligible:
Device driver support needs thus be built-in linux image!
If the problem is in the kernel -- if "make deb-pkg" always invokes
update-initramfs, but shouldn't -- let me know and I'll take this
issue upstream.
