Package: zfs-initramfs Version: 2.4.3-1 Severity: normal Tags: patch X-Debbugs-Cc: [email protected]
Dear Maintainer,
Ubuntu patches the busybox package to:
* add a busybox-initramfs binary package
* Prefer busybox cmds over klibc cmds where there is duplication
* Add static-sh alias name for ash (LP: #505887)
The busybox-initramfs package is smaller than the busybox package:
```

```
The size of busybox + glibc is a tiny fraction of Debian's initrd. The
main size comes from modules and firmware. These are significantly
larger than busybox. Therefore the busybox Debian maintainer does not
want to add a specific busybox build for initrds (see Debian #1135987).
Carrying this busybox delta in Ubuntu for the neglectable initrd size
difference is not worth the effort in 2026. So drop busybox-initramfs in
Ubuntu and make the initramfs-tools package simpler.
initramfs-tools recommends "busybox | busybox-static" on Debian and
Ubuntu now. So drop depending on busybox-initramfs and use the same
package order in Depends.
Git-formatted patch attached.
