Well, first off, if you have any sun slaves on there then simply don't. Same
with HP-UX - AIX seems to do file with a Linux master... Problems range from
corrupt dbs on slave servers to users not able to change passwords to random
login issues.
If your new master is currently a client You can also try just running a ypcat
and append that to the end of the existing password/group/hosts/whatever
file...
Otherwise just copy over the files you're currently generating maps from to
the new master in some temporary directiory. with the password & group file
just make sure you cut off the system accounts at the beginning of the
file....
Make sure you change groups if nessecary and if you need uid/gid < 100
published (i.e. HP-UX uses 20 as users group) you'll need to modify
your /var/yp/Makefile.
