Do not request initramfs-tools to build an initrd image for
user-mode-linux.
Building and installing a user-mode-linux Debian package with
make bindeb-pkg ARCH=um
apt install ./user-mode-linux-*.deb
fails reasonable due to missing kernel config in /boot
(KVER=6.13.0-rc2-00006-g8f2db654f79c):
update-initramfs: Generating /usr/bin/initrd.img-${KVER}
grep: /boot/config-${KVER}: No such file or directory
W: zstd compression (CONFIG_RD_ZSTD) not supported by kernel, using
gzip
grep: /boot/config-${KVER}: No such file or directory
E: gzip compression (CONFIG_RD_GZIP) not supported by kernel
update-initramfs: failed for /usr/bin/initrd.img-${KVER} with 1.
run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return
code 1
...
dpkg: error processing package user-mode-linux-${KVER} (--configure):
installed user-mode-linux-${KVER} package post-installation script
subprocess returned error exit status 1
Errors were encountered while processing:
user-mode-linux-${KVER}
E: Sub-process /usr/bin/dpkg returned an error code (1)
There is no need to build initrd for user-mode-linux, so stop requesting
it.
