Hi,
Since I have a laptop I choose fcron to sync emerge tree:
Code:
# ls -l /etc/cron.daily/
total 20
-rwxr-xr-x 1 root root   42 Feb 26 10:05 check_updates
-rwxr-xr-x 1 root root   52 Feb  4 18:49 logrotate.cron
-rwxr-xr-x 1 root root  115 Dec 14 23:55 makewhatis
-rwxr-xr-x 1 root root 1297 Dec 20 22:48 mlocate
-rwxr-xr-x 1 root root 2424 Jan 28  2012 prelink

but i syslog I can see only:
Code:
# grep -i daily  /var/log/messages
Mar  3 03:10:00 gopher run-crons[30296]: (root) CMD (/etc/cron.daily/makewhatis)
Mar  3 03:10:02 gopher run-crons[30345]: (root) CMD (/etc/cron.daily/mlocate)
Mar  3 10:58:16 gopher run-crons[2252]: (root) CMD (/etc/cron.daily/prelink)
Mar  4 08:50:00 gopher run-crons[6190]: (root) CMD (/etc/cron.daily/logrotate.cron)
Mar  4 08:50:01 gopher run-crons[6195]: (root) CMD (/etc/cron.daily/makewhatis)
Mar  4 08:50:02 gopher run-crons[6245]: (root) CMD (/etc/cron.daily/mlocate)
Mar  4 08:50:02 gopher run-crons[6250]: (root) CMD (/etc/cron.daily/prelink)

Here is my crontab for root:
Code:
# crontab -l

check the environment, and especially the PATH variable, while running it as cronjob.
I vaguely remember, that PATH for cron is comparably empty.

I've check:
Code:
# cat ~/dead.letter | tail
nice: check_updates: No such file or directory
Job nice -n 20 check_updates terminated (exit status: 127) (mailing output)

and adding full path to crontab solved the issue, but still I can't run scripts from /etc/cron.*/ directory

emc ...

Basically, with fcron 'systab' (ie what is generally run as /etc/crontab) is not root's crontab, note that /etc/crontab states "this is not the system crontab!". So, I think you may have added /etc/crontab as root's crontab.

Code:
# whoami
root
# crontab -l
2013-03-15 14:40:52  INFO listing root's fcrontab
2013-03-15 14:40:52  INFO user root has no fcrontab.

Also, the method used by fcron to handle the (system) crontab is dependent on the 'system-crontab' useflag, the behavior will differ dependent on the useflag (check the ebuild for details).

With '+system-crontab' the method of creating the 'systab' is to run 'emerge --configure sys-process/fcron' ... a /var/spool/fcron/systab should be created with the content of the current (system) /etc/crontab.

In your case I'm inclined to think that system-crontab is disabled ... but I'm not entirely sure.

best ... khay

I'm not 100% sure if I understood you. I have:
Code:
# eix -I fcron
[I] sys-process/fcron
     Available versions:  3.0.6-r1 ~3.0.6-r5 ~3.1.0 3.1.1 {{debug linguas_fr pam readline selinux +system-crontab}}
     Installed versions:  3.1.1(09:24:37 AM 02/19/2013)(pam readline system-crontab -debug -linguas_fr -selinux)
     Homepage:            http://fcron.free.fr/
     Description:         A command scheduler with extended capabilities over cron and anacron


So, should I use crontab for regular user (not root):

emc ... well, no, the 'system crontab' ('systab'), ie, what runs /etc/cron.{hourly,daily,weekly,monthly} and so all the package installed scripts therein, should be seperate from roots crontab (ie: that listed above with 'crontab -l'). When installing fcron you are einfo'd to run 'emerge --configure sys-process/fcron' which will take the content of 'system crontab' (/etc/crontab) and make a 'systab', /var/spool/fcron/systab, this is the 'crontab' that fcron will run for 'system crontab'. The other users can of course have their own crontabs, and these will show up as /var/spool/fcron/$(USER}.

I'm guessing the issues your having is that there are mulitple crontabs that run the same 'systab' at the same scheduled time. Actually, I'm not really sure whats happening, or why the content of /etc/cron.* isn't run ... but you seem to have the above misconfigured, so its no doubt a good idea to fix that before proceeding to debug it further.

I'd suggest stopping fcron, removing whatever currently exists in /var/spool/fcron, and running 'emerge --configure sys-process/fcron', once fcron is again started your 'systab' should run without issues, and the various users have empty crontabs.

Code:
% whoami
khayyam
% crontab -l
2013-03-18 11:24:14  INFO listing khayyam's fcrontab
2013-03-18 11:24:14  INFO user khayyam has no fcrontab.

Ok, it's getting clear, so what I did:

then:

And now I have question, since I'm running laptop so to best to my knowledge fcron is better (for system which can be turned off when cron task is scheduled) but in /etc/crontab I see:
Code:

So, should I run crontab /etc/crontab as root to get script from /etc/cron.{hourly|daily|weekly|montly} running?

I think text in /etc/crontam is misleading:
Quote:
# fcron:
# This is NOT the system crontab! fcron does not support a system crontab.
# to get /etc/cron.{hourly|daily|weekly|montly} working with fcron run
# crontab /etc/crontab
# as root.
# NOTE: This will REPLACE root's current crontab!!

Because system crontab is working without run: crontab /etc/crontab. I add some scripts into /etc/cron.hourly and they was successfully executed and there are entries in /var/log/messages. Anyway this close the topic ;)

khay thx for clarification and help :D

emc ... no need as the content of /etc/crontab has been transfered to the 'systab'. That note in /etc/crontab is a little bit misleading as when you install fcron, and /etc/crontab is installed, you are prompted to run 'emerge --configure sys-process/fcron', so following both suggestions you would replicate the content of /etc/crontab in 'systab' and in roots crontab.

EDIT: hehe ... I see you posted seconds before I made my reply.

I know it's solved but I have one more question... where can I change hour and minutes when {hourly|daily|weekly|montly} is started. Right now form daily is around 17:40:
Code:
# grep cron.daily /var/log/messages
Mar 24 17:30:01 gopher run-crons[8583]: (root) CMD (/etc/cron.daily/makewhatis)
