30This is a version of 'cron' that is known to run on most systems. It
31is functionally based on the SysV cron, which means that each user can have
32their own crontab file (all crontab files are stored in a read-protected
33directory, usually /var/cron/tabs). No direct support is provided for
34'at'; you can continue to run 'atrun' from the crontab as you have been
35doing. If you don't have atrun (i.e., System V) you are in trouble.
36
37A messages is logged each time a command is executed; also, the files
38"allow" and "deny" in /var/cron can be used to control access to the
39"crontab" command (which installs crontabs). It hasn't been tested on
40SysV, although some effort has gone into making the port an easy one.
41
42To use this: Sorry, folks, there is no cutesy 'Configure' script. You'll
43have to go edit a couple of files... So, here's the checklist:
44
45 Read all the FEATURES, INSTALL, and CONVERSION files
46 Edit config.h
47 Edit Makefile
48 (both of these files have instructions inside; note that
49 some things in config.h are definable in Makefile and are
50 therefore surrounded by #ifndef...#endif)
51 'make'
52 'su' and 'make install'
53 (you may have to install the man pages by hand)
54 kill your existing cron process
55 (actually you can run your existing cron if you want, but why?)
56 build new crontabs using /usr/lib/{crontab,crontab.local}
57 (either put them all in "root"'s crontab, or divide it up
58 and rip out all the 'su' commands, collapse the lengthy
59 lists into ranges with steps -- basically, this step is
60 as much work as you want to make it)
61 start up the new cron
62 (must be done as root)
63 watch it. test it with 'crontab -r' and watch the daemon track your
64 changes.
65 if you like it, change your /etc/{rc,rc.local} to use it instead of
66 the old one.
