Is it common for people to need to manipulate rpms on target without rpm being present using busybox? Do you know if busybox plans to add zstd support? As far as I could tell when we looked at this, the rpm world was moving over to zstd so adding in conditional xz support for a limited use case probably just creates a maintenance headache going forward as it isn't something we test or plan to test? Are you using this on an LTS release or master?
Hi Richard, After moving to Yocto Kirkstone (LTS) which we currently use, we started getting developer reports of 'no gzip/bzip2/xz magic' error from BusyBox applet. For example developer uploads an rpm file to target device and then unpacks it in runtime using 'rpm2cpio <somepkg.rpm> | cpio -idmv' command. We don't include rpm package on target filesystems as that would increase rootfs footprint approximately 5 MB. Including only rpm2cpio from rpm package needs still accompanying libraries, increasing the size by 2.5 MB approximately which also feels too big. I checked the discussions from BusyBox mailing list and found that in 2021 the maintainer seemed reluctant to accept the proposed zstd support because it was not optimized for embedded systems. http://lists.busybox.net/pipermail/busybox/2021-September/089179.html BR, Niko
