making sense of shit now definitely:
https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/tpm2-protocol.git/commit/?id=a0f2b3b7f70f6d1151a85c1fadaac5f181e09d91
I'm just learning Rust while doing, really discovered Deref and DerefMut while doing this transformation.

My favorite filesystems:
1. Ext4
2. FAT (and its various upgrades)
There's no operating system that could not read them I'm aware of.
Within last 20 years I've never had a situation where I'm in trouble because my machine does not have "advanced filesystem" :-) And basing backup strategy to local snapshots, well good luck with that. I have NAS.

@lkundrak ok except for zmodem i'm working on "bcachefs of zmodem implementations": https://codeberg.org/jarkko/zmodem2
:-)
i might continue from that to a replacement of https://en.wikipedia.org/wiki/SMODEM, which is the competitor to the pre-existing MS-DOS version of the protocol.

@lkundrak sounds like it's for smarter people than me, i would not pass the IQ test to become a legit power user of bcachefs ;-) what can you do if you're born as an idiot.

@lkundrak for this i chose rust because google made some nice tools for the dislayout itself: https://github.com/google/gpt-disk-rs
I was able to write a rus program that generates ESP+rootfs GPT partition layout to an image and then it with mkfs.ext4 and mkfs.fat generates partition slices of same size which I rewrite to the apprpriate slots.

does any of the ext4 crates for rust *initialize* a partition? I don't care of being able to read or write it, only "mkfs" part is interesting.

jarkkono SIZE constant anymore in the new TpmSized as no stack allocation is required:
/// Provides a `dyn`-safe way to get the exact size of a zero-copy cast object.
pub trait TpmSizedCast {
/// Returns the exact serialized size of the object.
fn len(&self) -> usize;
/// Returns `true` if the object has a serialized length of zero.
fn is_empty(&self) -> bool {
self.len() == 0
}
}
This ought to be renamed as TpmSized as full migration is over :-) Applies also to all other *Cast.

from nothing to something type of commit considering zerocopy semantics:

now it will be downhill :-)

i've finally found my preference for command line arguments in rust: argh. it's like "between the extremes". does not get in the way but neither does "overdo"

i created an experimental "slice and compose" style disk image builder just to build appropriate EFI bootable disk images for kernel testing. i might release this at some point once it "productizes"
