This sounds like you have a mislabeled system. Rawhide has
opened
today. see if the update fixes your problems, otherwise try
a relabel.
Now it is not selinux's fault:
[olivares@riohigh Download]$ crontab -l
cron/olivares: Permission denied
[olivares@riohigh Download]$ crontab -e
cron/olivares: Permission denied
[olivares@riohigh Download]$ dmesg | grep 'avc'
type=1400 audit(1238450106.840:4): avc: denied { read } for pid=1716
comm="dmesg" name="ld.so.cache" dev=sda5 ino=68454
scontext=system_u:system_r:dmesg_t:s0 tcontext=system_u:object_r:etc_t:s0 tclass=file
Wonder what could it be now?
Thanks,
Antonio
