Creating xfs and writing files to it?

[xnox]

Hi, w.r.t. superblock handing is this to create / parse / read the FS metadata only (aka equivalent of reading or possibly even writing data as it is seen after mkfs.xfs)?

Or can one also populate files?

I have been looking for anything that can write out xfs filesystem, without using a Linux kernel (and mounting a filesystem).

Hey lad, ltns :)

For now we're prioritising superblock detection. However as seen in luks2 we're planning to go further. Eventually I'd like opt-in std and write support for a number of filesystems and pull in the superblock crate for their data definitions.

First one will be erofs and maybe we can get the design right there then extend.

I think log and cache bits will fail to consumer domain and exposed / integrated via crate.

If I grok, you're looking to build complete filesystem images as euid!= 0 and bypass loop entirely?

Indeed long time no seen.

And yes, the dream is to be able to built filesystem / VM images, unprivileged, like one can do today for most part to build containers / .deb / .rpm / well they all are just tarballs more or less.

Yeah os agnostic artefact production is on my agenda, esp for CD.

Did I mention we're happy to have companies sponsor projects like disks-rs?

XD

btw there is such a thing as xfs_protofile https://manpages.debian.org/testing/xfsprogs/xfs_protofile.8.en.html and it can be used to populate xfs filesystems.

it would be nice to have a parser/writer/creator of that. In something better than what upstream xfsprogs has, cause they are loosing data, extended attriutes, labels, and timestamps.
