Re: encrypted root fs on a slug and crypto-modules



I don't know how much load you're going to put on your proposed Kerberos KDC, but the extra CPU load placed on it by encrypting the filesystem may make it unresponsive, given the Slug's not-very-fast CPU.

Let us know how it turns out.

After using my slug for some time to serve files with Debian installed
I thought I'd try using it for a kerberos kdc (tested and works ok) on
an encrypted root file system (current experiment). Not much load and
file access so this might be ok.

But for encryption during a fresh install on the slug, it seems the
installer fails to load some modules even though I have inserted an
extra media with a swap partition and initiated this partition for
swap before attempting to partition and encrypting the fs. In
particular three modules are not found

and a short investigation gives that it seems natural because they are
not built by the source package:
http://packages.debian.org/source/etch/linux-kernel-di-arm-2.6

But is this the only problem or is there some other flaw in my plan on
using an extra USB-memory for swap during the install? While the slug
is not really up to the task of acting as an interactive workstation I
have found that with swap it is surprisingly capable so I thought that
it perhaps could do the install given enough swap.

Thank you
Anders
