Am 21.09.2013 23:49, schrieb Canek Peláez Valdés: OK, so I conducted another experiment, to see if I was able to make systemd *not* to work with an exotic combination of underlying storage. I did the following: - 4 drives, all of them in RAID5. - The resulting /dev/md127 was put in a Physical Volume, that in a Volume Group, and that split into 5 Logical Volumes: 1. /boot (unnecessary, but why not) 2. swap 3. / (root) 4. /usr 5. /home - The /home partition was encrypted, and so was the swap. Everything works, but now I did had to do something not intuitive. First the intuitive changes from my previous experiment: 1. I had to put this in /etc/default/grub: GRUB_PRELOAD_MODULES=lvm mdraid1x Basically that's it. The partitions again use labels, so I didn't had to touch fstab, except for the not intuitive change. The problem, that I believe Stefan and Frank hinted, is that the encrypted swap did not activated properly, sometimes resulting in huge boot times (in the order of 1 minute). But only if you specify the swap partition in fstab. Yes, I reported this issue back then ... but I don't have the encrypted swap in /etc/fstab. I only have: # cat /etc/crypttab swap /dev/disk/by-id/ata-INTEL_SSDSA2M080G2GC_CVPO015404LR080JGN-part5 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256 which gives me a /dev/mapper/swap ... but no activated swap ... I will create a swap-unit now ... S

I understand that, yes ... it is unnecessary complex from my point of view as well. Swap that is encrypted from scratch everytime you boot up isn't the simplest thing ... but it is quite some fiddling, I agree ... Let's see if we can figure it out and document and/or patch it in a way that makes it easier for other users to use. This is still an early stage of systemd-adoption in gentoo linux ...
