Description: Accelerate Diskless Workstation systems by pre-loading a dummy Desktop Session
This package is for diskless Linux clients as you often find them in
school class rooms running an LTSP based fat client environment.
.
The logon into and the initial session startup on such diskless
workstations can be considerably slow, because all applications need to
be fetch from one server hosting the fat clients' filesystem.
.
The situation gets worse, if 24 computers in the same class room get
switched on simultaneously or the teacher tells the students to open the
same application (e.g. Libreoffice) at the same time.
.
However, this issue only occurs to the first student using a diskless
workstation that day. Other students see all applications launch within
a fraction of a second.
.
Reason: once an application has been launched, it ends up in the
diskless machine's filesystem cache in RAM.
.
This package, thus, pre-loads a desktop session of the admins choice and
some popular applications. It does it before 7:30 in the morning only.
So, combine this package with Wake-On-LAN to make sure systems are up
and the desktop session has been autoloaded (and quit) already before
the first students come into the class room.

some extra popular applications. It does this before 7:30 in the
morning, only. So, combine this package with Wake-On-LAN or an RTC Timer
to make sure systems are booted before 7:30am. With such a setup in
place, the diskless machines will have been prepared for work before the
first students enter the class room.
