i was able to reproduce this with current versions of ltsp, though i believe
the bug is actually in uswsusp's config script.
by running "ltsp-build-client --early-packages ltsp-client-core &> log", which
installs a smaller set of packages, i wasn't able to reproduce the problem.
running "ltsp-build-client --early-packages 'ltsp-client-core uswsusp' &> log",
triggers the problem again.

i think it occurs much later, as the log file gets truncated with the first
message being:
/sys not mounted. Can't create uswsusp.conf
followed by all the NULL characters.
i think it is uswsusp.config writing to stderr:
mountpoint -q /sys ||
{ echo "/sys not mounted. Can't create uswsusp.conf" > /dev/stderr; exit 0;
}
maybe using ">> /dev/stderr" would not truncate the log file, and fix the
issue?
live well,
