Welcome to the forum, duncant. The package is just not journald ready. However, since you have syslog-ng installed it should still be working I would reckon (just not with journalctl). Have a look here for info and alternative (last post): https://bbs.archlinux.org/viewtopic.php?id=151562
Don't mix and match old guides or ones for other distros, it only confuses - particularly for the init system. Specify the UUID for cryptdevice in the same format as you do for root, i.e. "cryptdevice=UUID=...".
It is using the aes-ni silicon. To compare the crypto performance of the two ciphers for your setup, have a look at cryptsetup benchmarkJudging from https://wiki.archlinux.org/index.php/SS … Partitionsyour crypt performance looks good though. However, take care to use the "conv=fdatasync,notrunc" with dd (see the examples on the wiki page).
