The reason Unix systems don't like numbers for names is because the
name is just an alias for a number that Unix assigns internally. Take
a look at the /etc/passwd file for example. Here's an example line
from my box:
nobody:x:99:99:Nobody:/:
This means that the user "nobody" is actually UserID 99, with GroupID
99, realname is Nobody and home directory is /
So, there is a good reason that Unix hates usernames that are numbers.
I don't know if manually creating one will do anything funky, but I'd
bet it won't work perfectly for some reason.
