I'm going to manually install Arch Linux from an ISO image on a KVM VPS that uses SeaBIOS. I plan to use grub2 as the bootloader.
My VPS will not hold important data that needs to be backed up. I don't need snapshots. If it has a failure that wipes out all data on disk, I'll just reinstall it. The applications are not disk I/O intensive. Most activity is network-related. I would like a lightweight filesystem.
The VPS provider advertises SSD storage (but I don't know for sure that my VPS is on SSD hardware).
What are the considerations I should keep in mind for picking the right file system? I'm going to guess I probably don't need a journaling filesystem. (I do want a file system that is in the Linux kernel.) What are the top choices I should consider in my situation?
I have not done the VPS installation yet, but I believe the file system choices will include btrfs, vfat, ext2, ext3, ext4, xfs, reiserfs, and probably more. In fact, unless the KVM virtualization environment imposes limitations, I should have available all the filesystems listed here:
