The branch stable/14 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=d32c600949d5891c014e9e794562e60caa2859f1 commit d32c600949d5891c014e9e794562e60caa2859f1 Author: Alexander Ziaee <concussious@runbox.com> AuthorDate: 2024-01-12 22:12:48 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2024-04-08 17:37:58 +0000 newfs_msdos.8: example for specific cluster size The usual use case in 2024 for newfs_msdosfs is creating filesystems on SD cards for older hardware. In most tutorials, they call the cluster size "allocation size". Therefore, add a small note next to cluster size that it is also called allocation size, and add an example for how to do this.
