✨ SAUNAFS-APPENDCHUNKS ✨

okay bestie, welcome to the saunafs-appendchunks page, aka the lazy append chunks era 💅 (that's the saunafs-appendchunks(1) manual, if we're being formal, which we are not)

🦋 NAME 🦋

saunafs-appendchunks — lazy append chunks

like, the chunks are lazy. they're napping. they'll get to it. no cap.

🌸 SYNOPSIS 🌸

saunafs appendchunks SNAPSHOT_FILE OBJECT...

that's it. that's the whole vibe check.

💖 DESCRIPTION 💖

so appendchunks (which is literally the same thing as sfssnapshot, they're twins, they share a brain cell 🫶) appends a lazy copy of the file(s) you specify into the snapshot file you specify.

and before you ask what "lazy" means — bestie, it means the creation of new chunks is delayed until the exact moment one of the copies gets modified. it's not lazy like me on a Sunday. it's lazy like efficient. it's giving "we'll deal with it when we actually have to" main character energy. 🔥

and if you hand it multiple files? iconic. it merges them all into ONE target file, and it does it in the most organized way possible: each file begins at a chunk boundary, and a chunk is 64MB. so file number two starts at 64MB, file number three at 128MB, and so on, forever, amen 🙏

the padding space is left empty. not zeroed, not filled with vibes. empty. it just sits there. minding its own business. 💀

😭 REPORTING BUGS 😭

found a bug? don't suffer in silence, bestie, that's not the move. report it to the GitHub repository at:
