Zur Bootzeit von Clients unter Gutsy habe ich im Blog von Oliver Gravert folgendes Erfreuliches gefunden:

We had some busy weeks in LTSP land recently and a lot of changes landed between ltsp version 5.0.8 and 5.0.17 So here comes the list with the new and shiny stuff we already have done upstream and merged into gutsy, enjoy:
Switched from nfs root to a squashfs compressed file exported via nbd (a technique we use for the network swapping since edgy already)
Dropping of the creation of various tmpfses on top of the readonly nfs root. We use a unionfs to merge the squashfs with a tmpfs now
Since gutsy there is no xorg.conf needed anymore, the creation of the X config was one of the most slowing down factors in the past, you can sill force X detection (CONFIGURE_X=True in lts.conf) , but we dont default to it anymore (it has proven to work fine on all tested clients so far)
Since we use a squashfs image and dont want our users to hae to run ltsp-update-image on every config change it is now possible to put the lts.conf file into the tftp dir under /var/lib/tftpboot/ltsp/$ARCH/
A competely new ldm written in C and Gtk with … (lots of thanks to Scott Balneaves for his new C backend)
Support for autologin
An option to disable the encryption of the X traffic (LDM_DIRECTX=True). With this option set passwords will still be handled encrypted but all X traffic is transported unencrypted. It is as fast as XDMCP but a tad more secure
A quater of the boottime the old ldm had
With the above changes merged a client (500Mhz/128M) that took 90 seconds from pressing the power button to providing a usable login screen now manages to boot to the same point in 44 secs.
