I'm not so sure about booting into custom init in <= 1sec since nobody really looked into optimizing the boot process that much yet, but Arch in 5 secs should be easily achievable since booting Jumpdrive on Librem 5 with regular u-boot takes about 5-6 seconds already with no effort put into booting speed whatsoever. Just getting rid of initrd would already shave quite a lot of time. Librem 5 has a slightly faster CPU, more than twice as fast RAM and pretty much the same eMMC speed as the PinePhone. Boot times should generally be similar, with Librem 5 slightly winning, and that matches my observations so far with similar distros running on both devices. No videos yet though, I may record some in the future :)
