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.

I installed Fedora 39 on an old iMac I had with a fusion drive (128GB SSD +1TB spinning disk.)

Fedora is installed on the SSD, and I want to use the spinning disk as a media drive. Problem is, it does not mount by default, so I figure I need to edit /etc/fstab to have it mount at startup.

I’m at work so I SSH into the iMac and get the UUID for the disk and then open fstab in vi, enter the new line with the uuid, directory I want the drive mounted in (/media), the filesystem (ext4) and the options. Try to write and quit, get an error the file is readonly. Try to set the file to noreadonly, write fails again. Try :wq! and get the error the file cannot be opened to write.

Exit vi, ls -la and see the file is read-only.

sudo chmod 644 fstab, put in password. ls -la shows file is still read only. lsattr fstab, immutable flag is not set.

Is this happening because I’m on SSH, or is there some other issue?

Try remounting the root filesystem with "mount -o remount,rw /".
