Is it normal to set up a user that is a member of sys, in this case kim, so that that user can do system maintenance?
yes, the wiki suppose that bootes is that special *user", I have a cpu/auth/fs server where "fgb" is "bootes".
Or, should I log in as sys when I need to do maintenance? Should I assign passwords to sys and adm? Normally I would think so.
no, you should login as the user you want to be the hostowner, typically bootes. ah, just in case, a typical error that people usually get is something like "server lies" because some pass don't agree. that's due to a mistmatch in the passwd you typed when you rebooted after you echoed jklds > /dev/sdC0/nvram good luck and welcome to Plan 9 -- Federico G.
