I do not have a reference, I just discovered things with experience:
/etc/crypttab should contain something like:
luks-XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX none
/boot/grub/grub.conf should contain on your kernel line the part
rd.md=1 rd.dm=1 rd.luks=1
or at least the luks one
then I rebuild the initramfs; the way to do this is continuously changed so my
method is to run rpm -q --scripts kernel and look at the posttrans part:
posttrans scriptlet (using /bin/sh):
/sbin/new-kernel-pkg --package kernel --mkinitrd --dracut --depmod --update
3.14.17-100.fc19.x86_64 || exit $?
/sbin/new-kernel-pkg --package kernel --rpmposttrans 3.14.17-100.fc19.x86_64 || exit $?
so I run those two commands.
Sorry for not giving an accurate procedure, but those are the points to consider.
No problem. Thank you. this is very helpful. Btw, isn't the recommended way to edit
grub by changing /etc/defaults/grub and then running grub-mkconfig or is that for
something else?
Best wishes,
Ranjan
