gensquashfs pipe #46

Closed i0x71 closed 4 years ago

i0x71 commented 4 years ago

Hello, Is it possible to pipe put the output of gensquashfs to stdout ? I have half a terrabyte of files that i would like to make into a squash image and pipe them into an s3 client, storing it in a local image file would take up unneccessary space.

Thanks

Unfortunately no. A SquashFS image has the meta data describing the directory tree at the end, after the compressed data, and the super block that describes the location of the meta data at the beginning, before the compressed data.

When generating a SquashFS image, you need the ability to seek back to the beginning and update the super block when you are done. This cannot be done if the output is a pipe.

This has been discussed in more detail in #24.
