From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux doesn't serve birth time attribute over NFS (discuss.tchncs.de)

According to this Phoronix article, Linux should support the birth time attribute in the NFS server since 5.18. However, it doesn't show up in the stat output when looking at the file through the NFS mount, or elsewhere (at least, the Dolphin file browser and also a macOS client):

% stat file
  File: file
  Size: 0               Blocks: 0          IO Block: 1048576 regular empty file
Device: 0,70    Inode: 103416894   Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1000/   saiko)   Gid: (  100/   users)
Access: 2023-12-17 03:22:45.368950609 +0100
Modify: 2023-12-17 03:22:45.368950609 +0100
Change: 2023-12-17 03:22:45.368950609 +0100
 Birth: -

What gives? Running stat on the server directly, it shows the attribute. The backing file system is ext4, kernel 6.5.12. The client is using kernel 6.1.63.

[coreutils-announce] coreutils-8.31 released [stable]

stat now prints file creation time when supported by the file system,
on GNU Linux systems with glibc >= 2.28 and kernel >= 4.11.
