Public bug reported:
I have a small 100MB boot paritition and an initramfs that is 37MB. Once
you add in all the usual clutter in /boot there is 25MB or so of free
space left. I have a single kernel installed, there are no older
versions floating about.
When I run the update-initramfs script, it fails with :
gzip: stdout: No space left on device
E: mkinitramfs failure cpio 141 gzip 1
update-initramfs: failed for /boot/initrd.img-4.4.0-21-generic with 1.
Looking at the default update-initramfs script, it appears to try and
create the new initramfs image on the boot partition, then rename it to
the current one in use. It fails at the cpio step as there is
insufficient room for both initramfs images in the partition.
I have tweaked the script to allow it to create the initramfs image in
/tmp and then move it to the desired location (as opposed to creating it
/ renaming it in the same location), however while it works for me (tm)
I'm unsure if this breaks any other behaviour.
