=====Splitting Dm-crypt_with_LUKS=====

Hi, I thought you may be interested in participating to [[Talk:Dm-crypt_with_LUKS#Splitting_sections_into_separate_pages]] :) -- [[User:Kynikos|Kynikos]] ([[User talk:Kynikos|talk]]) 02:56, 30 September 2013 (UTC)

:Oh, a new LUKS plan. Thanks for the heads up. I can't right now but will join in asap/24h. --[[User:Indigo|Indigo]] ([[User talk:Indigo|talk]]) 05:26, 30 September 2013 (UTC)

I am writing this as I frequently edit disk encryption wiki pages here and want to gain some input on upcoming news and hopefully help to minimize disjunct editing:
+
 
+
Systemd is evolving a lot. One recent change has been the new {{ic|systemd}} hook. It simplifies a lot of setups, but is not compatible with a number of older hooks. One of those is {{ic|encrypt}}. Now [[User:brain0]] is thankfully working on a new hook {{ic|sd-encrypt}} to remedy that. While that has one big advantage of using systemd backend, i.e. {{ic|systemd-cryptsetup-generator}}, to setup the encrypted devices, it also is not compatible in the kernel command line options. So, these and the mkinitcpio configuration advice have to be changed to show the new options on various pages. 
+
 
+
Now how do we handle this on the various wiki pages on disk encryption? Imo a reasonable way would be to add a respective alternative for the {{ic|mkinitcpio}} and bootloader sections of the disk encryption wiki pages. However, it would be good in my view to give a general advice on '''when''' and '''how''' to use the new hook. Likewise this should detail when the old encrypt should be used.
+
 
+
So, question (1): what should that general advice contain? E.g. which other hooks (a setup might need) are known not to be compatible with the {{ic|systemd}} and, hence, {{ic|sd-encrypt}}. Keyboard, keymap? (sd-vconsole I saw is going to be added). How about mdadm_udev, lvm and resume? Others?
+
 
+
Question (2): In my view it would be very preferable to have the general configuration advice in one place, so that the specific disk encryption pages do not have to go to lengths but can crosslink and just state the two alternatives where available. A good place for this should be [[Mkinitcpio]], which can be referred to by the disk encryption pages. But the hooks are explained there very brief in a table. Other good options?
+
 
+
Question (3): I have not tried it, but I was wondering what the new option of having a {{ic|/etc/crypttab.initramfs}} entails. What is a usecase where one might want to use that? The usual way of crypttab being parsed during boot is not affected by the change to {{ic|sd-encrypt}} I reckon.
+
 
+
Thanks for input on 1,2,3 and other points you might see. --[[User:Indigo|Indigo]] ([[User talk:Indigo|talk]]) 20:30, 4 October 2013 (UTC)

:Ad (1): Basically all runtime hooks (those in {{ic|/usr/lib/initcpio/hooks/}}) are not supported by the systemd hook. I guess they would have to be ported to systemd units to be actually executed from the initrd. Some install hooks (those in {{ic|/usr/lib/initcpio/install/}}) are probably unsupported too. -- [[User:Lahwaacz|Lahwaacz]] ([[User talk:Lahwaacz|talk]]) 06:36, 5 October 2013 (UTC)

::Thanks for the input. I am hoping to collect such so that we can make an appropriate wiki task for it. Of the runtime hooks  {{ic|shutdown}} appears to work. One major question appears to be the status for LVM and mdadm/_udev.
