I totaly agree with you but i do not have the choice, you import program is in
conflict with import from imagemagick. So, under Archlinux system (i'm based on
it) the bin directory is a symlinks to /usr/bin.
note : I think, you will have this trouble on a lot of distribution. you have
importas program which do the same thing as import program, so perhaps you can
remove the import program?!?

my fault,it is not a down file but a finish file, type syntax error here :)

i taken your original service from your s6 package, i do not have changing
anything on it appart the s6-setuidgid at the log scripts that i defined with
s6log according to my system. However, if i try with your klogd-linux service,
the error is equal. So, this is the procedure i use, perhaps i make a mistake :
i copy the entire directory syslogd-linux to my running scandir
/run/boot/service
then i enter this command on the console:
s6-svscanctl -an /run/boot/service

for the moment i do not understand what you mean :(.
Well i cannot start another s6-svscan (for user) on the init file rather than
by a oneshot, because i need to wait for a complete operational system. I don't
find the solution to tell at all the service on the user s6-svscan to wait that
the last oneshot service for the booting time must be ready(not sure i'm clear,
difficult in english for me).
i would like to separate the database for the boot and a database for a user.
to make this i need to create a s6-svscan directory which allow me to start a
rc database. But same thing, if i put the command to launch the s6-svscan dir
on the init file, the system is not ready.
