The result was that Xiafs changed very little while ext2 evolved considerably, rapidly improving stability and performance, and adding extensions. ext2, after some shakedown time, quickly became the standard file system of Linux. Since then, ext2 has developed into a very mature and robust file

Xiafs was less powerful and offered less functionality than ext2. The maximum size of a file was 64 MiB and the maximum size of a partition was 2 GiB. While this was an improvement over ext, it did not measure up to ext2. Xiafs used less disk space for its control structures and it had greater

file system, but it had a number of limitations. For example, the length of filenames was limited to 14 characters and the partition size was limited to 64 MB. To replace the MINIX file system, the
