>Description:
I setup lpd to print to a remote printer. My system uses all ZFS so the spool directory is on ZFS too. After initially setting it up, lpd runs, but does not print. Also, I get an error from lpq saying "cannot examine spooling area"
>How-To-Repeat:
1. Setup an all ZFS system.

2. Add these lines to /etc/printcap:

lp|hp1320:\
        :sh:\
        :rp=lp:\
        :mx#0:\
        :rm=hp1320:sd=/var/spool/output/hp1320:lf=/var/log/lpd-errs:

3. FInish configuring lpd:

echo 'lpd_enable="YES"' >> /etc/rc.conf
mkdir -p /var/spool/output/hp1320
/etc/rc.d/lpd start

4. Try to print:

lptest | lpr

5. See printing does not happen.

6. Also see error from lpq:

% lpq
lpq: lp: cannot examine spooling area

>Fix:
Work around is to put the spool dir on a UFS file system. Even one backed by md works.
