Package: initramfs-tools
Version: 0.133
Severity: normal
Dear Maintainer,
On systems with a small /boot volume, update-initramfs will frequently fail
with
pigz: abort: write error on <stdout> (No space left on device)
This hasn't been an issue so far, with a 200MB boot volume and a maximum of 2
kernels kept.
But now, I have encountered it on several systems that need a separate /boot
partition, on 2 different CPU architectures.
After the new initramfs is generated, it will fit on the small /boot without
problems.
This leads me to the conclusion that update-initramfs stores temporary files on
the volumes - I don't think it should do that.
Please make sure that uncompressed images, temporary files, etc. are stored on
a volume that does not have dire size constraints, such as /tmp or similar.
Thank you.

initramfs-tools doesn't store temporary files on /boot.
In case it is replacing an initramfs for a kernel version that already
has one, it will create the new image before deleting the old one.
This is intentional and will not be changed as it could make the system
unbootable.
It might make sense for you to put "MODULES=dep" in initramfs.conf, to
reduce the size of each initramfs.
