Could it be linked against dietlibc or ulibc? Anyway, I will add the data
above to a footnote in the paper.

Fixed. Thanks for spotting this problem. Also fixed in the proposed
minimum telinit interface.

Actually, I do know that if you leave runlevel 2 and enter runlevel 3,
runlevel 3's K scripts will be executed. That passage in the paper was
poorly written, I will rewrite it to clarify this point.
Hrmm, I guess I should add the revision log to the last page of the paper,
now that there are non-cosmetic updates :)

Yeah, I recall you told me this. Well, you could name them: sysvinit-init
(for init/telint and other related stuff), sysvinit-rc for the
startup/runlevel manager, and initscripts-base for the init scripts
This way, we have file-rc depending on sysvinit-init and initscripts-base,
and conflicting with sysvinit-rc.
