We have all our clients automount one of our server's /var/spool/mail onto their own /var/spool/mail, then specify in /etc/sendmail.cf that all mails should be forwarded to that server host, regardless of incoming or outgoing mail. According to the man page of flock(2), fcntl(2v) and lockf(3) both make use of lockd, except flock(2) itself. I have experienced reading mails while getting biff to notify me of new mail, and quitting with deleted mails and so on wouldn't mess up my /var/spool/mail/<user> file and my mbox file. My users here have never reported problems about mail messing up so far. We have been running 4.0 since August and so far so good. I don't see noticeably difference of performance in the general sense, except sunview starts up slower than before. There are quite a lot of nice things to us though, like supporting different netmasks on different ie?s in ifconfig, discarding nd and the use of nfs for clients, faster dump, reduced load module due to dynamic library, etc. But some third party softwares might not take this advantage, like kcl which has to be compiled with -Bstatic. Oh, yeh, automount in 4.0 is very handy for file system migration and user home directory relocation. To be fair, I would argue 4.0 is pretty ok at least at my site.
