I paid little attention to this since I had to reinstall the distro few weeks ago and just formatted all the drives XFS out of laziness
Before the SSD (a nvme gen 3) was formatted F2FS and booting from GRUB to desktop took 6 seconds. Now on XFS it takes about 18 seconds, with a brake of no i/o activity after the uefi logo dissapears, before X starts up.
System i/o performance and speeds are 100% the same. It has been also very reliable, no corruption after a couple power outages.
If anyone is curious, here is the most recent journalctl boot log nov 20 20:23:22 arch-b450aorusm kernel: Linux version 5.9.8-2-MANJARO (builduser - Pastebin.com
This is merely a small annoyance but I would be interested in a fix, workaround, or if not, how can I migrate to another filesystem?
Can I just copy all the files of / to an image formatted as another filesystem, then restore it, edit fstab and it shlould just work?
