It appears that the directories used by apsfilter conflict with the
current policy.  The installation script, apsfilterconfig, installs
separate log and accounting files for each printer, under
/var/spool/lpd/PRINTERNAME/.  These separate subdirectories are named
in the /etc/printcap installed by the script.

After reading the FHS document, and looking at /var/log, it appears to
me that the log files at least (and probably the accounting as well)
should go in /var/log/lp-acct and /var/log/lp-errs, or perhaps in
/var/log/lpr.log.

If these directories are to be changed, I think it can be done just by
editing the SETUP script used by apsfilterconfig.
