• You can check whether running or not , check it by using ps ax | grep crond
• If it’s not running at start up, add it into /etc/rc.local then at it into /etc/init.d/crond start
• edit your crontab using command crontab -e
• list of your crontab using crontab -l
• if you found unable to save because not enough disk space at your linux OS, then check it using df -i or df -h
• find your below 8k files using find /var -size -8k , then delete it using find {trouble directory} -size -8  -exec rm -f {} ;

You can put your first time script crontab. Make sure your crontab daemon is already started. To start, type this /etc/init.d/crond start

Nyoba jalanin Fedora Core 10 di laptop compaq presario. USB kedetect, dan dengan lancarnya bisa booting sampe suatu ketika ada tulisan seperti itu

 [...]
    Loading vmlinuz0 .........
    Loading initrd0.img ........
    Ready
    Memory for crash kernel (0x0 to 0x0) notwithin permissible range
    pnp: PnPACPI: METHOD_NAME_CRS failure for PNP0c01
    udev[454]: add_to_rules: unknown key 'ATTRS{media}'

    #-- The "Memory for crash kernel ..." and the "udev[454]: add ..."
    #-- also appear during my laptop's boot; the "pnp: PnPACPI ..."
    #-- does NOT appear on any laptop which boots fine beyond this point.
    #-- Below is the remaining sequence for a desktop Live CD boot

    --------------------------------------
    WARNING: Cannot find root file system!
    --------------------------------------

    Create symlink /dev/root and then exit this shell to continue the
    boot sequence.

    bash: no job control in this shell
    bash-3.2#

dan kalo misalnya kita bikin symbolic link ke / hasilnya malah begini

    mount: special device /dev/root does not exist
    Bug in initramfs /init detected. Dropping to a shell. Good luck!

    bash: no job control in this shell
    bash-3.2#

akhirnya setelah lama ngutak ngatik di web, ternyata persoalan diatas diakibatkan adanya controller IDE / CDROM yang pake controller SATA. Jadi untuk harus ada init string yang diganti pada saat sebelum proses booting. Silahkan ganti root=UIDxxxxxxx dengan lokasi usbnya yang biasanya ada di /dev/sdb1. (ini ada di menu Grub).

Mudah – mudahan berhasil…kalo gw sih berhasil
