I am currently considering installing Ubuntu Server 18.04 LTS on a new box that will be very I/O intensive (multiple Samsung 970 Pros used for a crap-ton of random R/W I/O), instead of the usual CentOs (with its ancient 3.x series stock Linux Kernel). I was wondering what stock kernel Ubuntu Server 18.04 LTS will be packaged with?
I know that Ubuntu 18.04 LTS itself has a pretty recent kernel and am wondering what the Ubuntu team chose for the Server release.
The same kernel. It's the same distribution.
The only difference between the server media and the desktop media is the installer, and the default set of packages. The repositories and software versions is identical.
From Ubuntu Server FAQ:
Before 12.04, Ubuntu server installs a server-optimized kernel by default. Since 12.04, there is no difference in kernel between Ubuntu Desktop and Ubuntu Server since linux-image-server is merged into linux-image-generic
https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes#Linux_kernel_4.15 specifies it comes with the 4.15 kernel.
