4.8-STABLE /dev/null issue
sk at isprime.com
Wed Jun 4 11:48:28 PDT 2003
I've followed those instructions and still a no go. Enabled my crontab
* * * * * echo blah >/dev/null
And this is what happened:
crw-r--r-- 1 root wheel 2, 2 Jun 4 14:45 /dev/null
Subject: Cron <sk at diamond> echo blah >/dev/null
cannot create /dev/null: permission denied
If anyone else has some suggestions, please let me know. This is starting
to become a rather big issue on 4.8-STABLE for me.
