| Yes, order is important, as the options will only affect logfiles that come after them, and since most of your logfiles are defined in logrotate.d, the compress option comes too late.
To uncomment the existing compress option with sed, just use:
sed -i 's/^#compress/compress/' /etc/logrotate.conf
An easier (and more reliable) technique, however, is to add your option overrides to a file that gets included before any of the other included files, like so:
echo "compress" >> /etc/logrotate.d/000-local-overrides
That way you don't have to worry about figuring out whether the commented out option is in the config file or what to do if someone has added a space after the comment character.

at the end of my kickstart .cfg file, i have a line (its actually the final line)
echo "compress" >> /etc/logrotate.conf
EOF
which causes my /etc/logrotate.conf to look like this:
[root@psl-sipas04 log]# cat /etc/logrotate.conf
# see "man logrotate" for details
# rotate log files weekly
weekly
# keep 4 weeks worth of backlogs
rotate 4
# create new (empty) log files after rotating old ones
create
# uncomment this if you want your log files compressed
#compress
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp -- we'll rotate them here
/var/log/wtmp {
monthly
minsize 1M
create 0664 root utmp
rotate 1
}
# system-specific logs may be also be configured here.
compress
[root@psl-sipas04 log]#
as you can see, the 'compress' is the last line of the .conf file. but despite the fact its there, the server(s) is not compressing the log riles upon rotation. ive been under the impression that the exitance of a 'compress' in the uncommented state would cause the behavior i want, but this appears to not be so (not sure why here, other research required).
im wondering if i use something other than echoing the compress to the end of the file, or if i use awk or sed to locate the...
#compress
and change it to...
compress
if that would help?
would anyone be able to help me with an example that would do this at the post of my kickstart, instead of just appending the 'compress' at the bottom/end of file?
