Frequently Asked Questions
Does bcachefs support ACL/xattrs ?
Yes it supports both ACL and xattrs.
Do I have to reformat my bcache drive to use the new bcachefs ?
To use the caching device (cdev) with the new bcachefs, you will need to reformat it. In principle this should not be a problem, as they can be removed from a backing device (bdev/bcache).
If you wish to reuse the backing device (bdev/bcache), you can't this is nolonger an option.
If you wish to use bcachefs as a filesystem you will have to format the backing device (bdev/bcache) with the new filesystem.
Does bcachefs still have the bcache caching functionality of block devices ?
Where do I obtain statically linked bcachefs-tool (for use in initramfs) ?
You can either compile them yourself from source, or refer to your distribution on how to obtain a statically linked set.
About: Statically linked programs have all the required dependencies compiled in. As such, they require no external libraries at runtime. This does however increase the size of the binary.

I get the error "tools-util.c:16:19: fatal error: blkid.h: No such file or directory":
You might need to add EXTRA_CFLAGS="-l/usr/include/blkid/" or where-ever your OS stores the blkid.h file.
