Hi, an addendum:
utmp and wtmp have a 8 character limit for the username.
utmpx and wtmpx, which I think we have since last century,*
have 32bit limit, so if your tools use the latter log files,
you're safe with 32 character username. If you exceed the limit,
last(8) etc. will only show the truncated name.
see utmpx(5)
