better-initramfs update ?

[jeandestouches]

Hello, Are you planning to update better-initramfs? There are a couple of updates available since last release. Only one without update being vconfig if I'm correct.

alpine 3.14.2 > 3.17.2

busybox 1.33.1 > 1.34.1
cryptsetup 2.4.0 > 2.4.3
dropbear 2020.81 > 2022.83
json-c 0.15 > 0.16
libaio 0.3.112 > 0.3.113
libblkid 2.37 > 2.38.1
libgcrypt 1.8.8 > 1.10.1
libgpg-error 1.42 > 1.46
libuuid 2.37 > 2.38.1
lvm2 2.02.188 > 2.03.19
mdadm 4.1 > 4.2
popt 1.18 > 1.19
zlib 1.2.11 > 1.2.13

Thanks! Cheers

Yes, I just found the project to be mostly feature completed and I do not invest much time into it. There's however many parts that I'd like to entirely rewrite, and add static eudev for proper /run/udev that is then required for systemd and lvm running under systemd.

Anyhow thanks for showing interest, I've just pushed update with new sysroot, I will update deps to new versions and maybe finally add some distfiles checksum validation while at it too.

I'm really glad to hear that @slashbeast, I have been working on it on my own as well.

BTW have you had a chance to revisit my PRs for ip4ll and dns? I was thinking of just rebasing and combining my networking updates, since they are behind master now.

Thanks @slashbeast I forgot to mention missing ecdsa support for dropbear but noticed you added it already, nice. https://github.com/slashbeast/better-initramfs/commit/732c3617417762faffb60e53683d4404bf1d9303

I personally added a kexec-tools lebuild a few months ago to be able to kexec to a different kernel (or pass kernel options) straight from initramfs. It works fine. I don't know if you feel like to add it ? Otherwise, I just let this here for those interested to try.

Size of the compiled binary : 255K

It might make sense if better-initramfs will get features similar to https://github.com/open-power/petitboot but I do not see use for it. So I will leave it out, however if you feel like it might be of use for others feel free to make pull request with lebuild just leave it out of default installation list for now.

[fff7d1bc]

FWIW it is still on my radar of things to do in near future, along with eudev support so finally the systemd can get proper /run/udev from initramfs.

[unqueued]

Well it has been like four years, but I reviewed everything. When binit_net_addr=dhcp is set, then nameservers will be set automatically, unless one or more binit_net_nss has been set. I also included link-local support from https://github.com/slashbeast/better-initramfs/pull/49, since that is usually included in dhcp clients anyway, and wouldn't be unexpected. Let me know what you think.
