Thank you for the reply!
As Xiang pointed out, we believe that uncompressed support for EROFS is still
valuable, so I would be very grateful if this support could be merged into the
GRUB mainline.
Yes, I believe this will get merged into master. The question is
"when", after or before release. Now that I know that the compression is
on a per-file basis and so this version can still be widely used (with
the condition that the kernel and initrd are uncompressed by EROFS), I
am in support of having this included in the upcoming release.
Ultimately the decision is Daniel's though.
ping.. May I ask what's your opinion of EROFS uncompressed support
for GRUB. I assume compressed EROFS support needs more work to do,
so could we support uncompressed support as the first step since
EROFS supports per-file compression configuration?
The v4 version is already finished with Glenn's RVB:
https://lists.gnu.org/archive/html/grub-devel/2023-07/msg00102.html
By the way, we expect to bring support for the EROFS compression part within a
few weeks. However, AFAIK, GRUB lacks generic support for lz4 compression
algorithms. Would it be more appropriate to introduce a dedicated lz4 library
for EROFS, like zfs, or generic lz4 support for grub?
I have not looked into ZFS's usage of its internal library, nor how
hard it would be to make it a separate module. But I prefer the
separate module approach. Perhaps Daniel can speak to his preferred> method.
same here.
Thanks,
Gao Xiang
