User-Agent: Mozilla/4.75 [de] (X11; U; Linux 2.2.16-3 i686; Nav)


/etc/init.d/lpd calls checkpc -f, which hangs an printer ports
like /dev/irlpt0. The open is blocked until a IRDA printer is
in range.

Reproducible: Always
Steps to Reproduce:
1.Configure a IRDA printer in printcap (/dev/irlpt0)
2.Start /etc/init.d/irda
3.Start /etc/init.d/lpd
	

Actual Results:  The system won't boot until an IRDA printer is recognised
by
the IRDA kernel stack and thus the open() performed by 'checkpc -f'
is returned.

Expected Results:  System should start.

Use either non-blockig open() in checkpc or comment out
the line in /etc/init.d/lpd

this 'should' work now, but havent tested it. Try LPRng from rawhide, and reopen
if this is broken.
