Hi,
I'm after some info regarding encrypted root & home partitions with Arch Linux, using the LUKS encryption system (as documented here: http://wiki.archlinux.org/index.php/LUKS_Encrypted_Root).
1. Is there any kind of noticeable performance impact on a) boot times b) post-boot general OS speed. Say for example i have a 200gb home partition, that gets decrypted on boot does this take long?
2. How does LUKS relate to file system, I mean can i still use ext3 or is a special file system required.
3. If the system is decrypted on boot, I'm assuming it gets re-encrypted on shutdown, so what happens if the power cuts off and there is a bad shutdown, any risks of corruption?
Thanks for any help,
Jack
