>Description:
Executing "crontab <file>" fails due to a permission error:

| crontab: cannot create `tabs/tmp.00010572aa': Permission denied

The permissions on "/usr/bin/crontab" are correct ("-r-sr-xr-x", owned
by root), and "crontab -e" works fine.
>How-To-Repeat:
As an unprivileged user, execute the following commands:

	echo '* * * * * /usr/bin/true' > /tmp/crontab-example
	crontab /tmp/crontab-example
>Fix:
Unknown.

 PR/46127: Holger Weiss: "crontab <file>" fails for unprivileged users
 XXX: Pullup to 6
 Fix multiple problems in previous commit:
 1.) Correct set-uid check to allow "root" to run "crontab -l" again.
 2.) Don't the the last error reported in "errno" in case "crontab" is not
     installed set-uid "root". As no system-call failed "errno" is set
     to zero.
