David Heinemeier HanssonandClaude Fable 5 f97a664ea3 Unpack the live initramfs synchronously
Kernel 7.1 unpacks the initramfs asynchronously, which races /init: the
early /proc, /sys, /dev, and /run mounts fail with EPERM while unpacking
settles. In the live environment that kills Plymouth and leaves early
archiso mounts to luck. Force synchronous unpacking on every boot entry,
matching the fix shipped for installed systems in omarchy-defaults.conf.
