Bug#989143: initramfs-tools: doesn’t actually compress with zstd
Package: initramfs-tools
Version: 0.140
Severity: normal
Hey.
Just noted by coincidence, that even though I have set:
COMPRESS=zstd
and zstd is installed and even runs (seen in e.g. top utility) when running
update-initramfs -u
the files are in the end nevertheless plain cpio:
file /boot/initrd.img-5.10.0-7-amd64
/boot/initrd.img-5.10.0-7-amd64: ASCII cpio archive (SVR4 with no CRC)
Cheers,
Chris.
