docs/composefs: Document zstd:chunked pull limitation - #2409
Merged

Images published with --compression-format zstd:chunked fail to pull
on the composefs backend ("unexpected EOF reading tar entry") because
composefs-rs's decompressor only reads the first zstd frame. Note the
limitation and the workaround per issue bootc-dev#2408.

(The question is if we'll remember to remove this when we apply the fix...) |

The docs entry links #2408, which can't close until a composefs-rs update brings the fix in, so that's the standing reminder; I'll send the removal PR alongside that and close it out. |

The composefs backend cannot currently pull zstd:chunked images (#2408): the decoder stops at the first zstd frame, so the pull fails with "unexpected EOF reading tar entry". Note the limitation, the fix in flight, and the publisher-side workaround under Known Issues.

I measured the limitation on my own host and reviewed the line.
