i always figured that if you
(1) do all the moves and creation of new (empty) log files
(2) do all the hupping (syslogd, and others) [*]
(3) do all the gziping (bzip2ing?)
that there would be no need for locking. or are you trying to guard
against to instances of newsyslog running simultaneously not stepping
on each other's toes?
[*] the alias in root's .cshrc call 'hup' is not quite correct (imho).
alias hup 'kill -HUP `cat /var/run/\!$.pid`'
but i feel that
alias hup 'kill -HUP `head -1 /var/run/\!$.pid`'
would be better, since some things (sendmail, others?) store more than
just a pid in there. unless, of course, i'm simply expected to ignore
the errors that kill gives me from that.
