I added "usermod -G lp dsl" to bootlocal.sh in an attempt to add the user dsl to the group lp (which may or may not be required for some aspects of hplip printing).I just noticed that I get the following in /var/log/messages:

I guess I should reformat the usermod command, but how?

From the man page, -G option: if user is a member of any other groups than listed, he'll be removed from them. To prevent this and only add the user to a new group, see the -a option.So add -a to that command and everything is okay

Must be a busybox/older ver... Then you'll just have to add by hand (edit /etc/group) to avoid listing all the groups..
