@sil2100 zstd depends was added in the devel series. Historically, we only had the depends on the tool that is needed at a time for a given series... ie. gzip, xz, lz4, zstd.
Given that zstd compressed initrds are not supported by the linux GA kernel in Focal, I am hesitant to impose zstd dependency on everyone in focal. Only .3 hwe will have support for zstd compressed initrds. Note we don't add depends on other compression methods that are supported either, ie. bzip2. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1932542 Title: Add support for zstd Status in initramfs-tools package in Ubuntu: Fix Released Status in initramfs-tools source package in Focal: Fix Committed Bug description: [Impact] * initramfs-tools in impish has changed default initrd compression to zstd. To allow compressing and uncompressing such initrds on Focal LTS release we should backport zstd support in the mkinitramfs & unmkinitramffs tooling. For example ubuntu-cdimage uses unmkinitramfs tool to unpack and inspect impish initrds on a focal host. * Cherrypicking the feature from 0.138 release, which is also present in Hirsute and Impish. [Test Plan] * Create initrd with zstd $ mkinitramfs -c zstd -o zstd-initrd.img * Uncompress it with $ unmkinitramfs ./zstd-initrd.img zstd-initrd- unpacked [Where problems could occur] * This adds support for zstd compressed initrd in both mkinitramfs and unmkinitramfs. However our GA kernels do not support zstd compressed initrds. And depends on zstd package is not added either. Meaning one still has to install zstd to gain the unpack support. Changing initramfs.conf to zstd may result in unbootable instance when used with GA kernel.
