System: NetBSD armandeche 1.4P NetBSD 1.4P (ARMANDECHE) #1: Sun Dec 19 20:26:10 MET 1999 bouyer@armandeche:/home/cvs.netbsd.org/src/sys/arch/i386/compile/ARMANDECHE i386


>Description:
	
	I have the followig directories exported:
	/home/cvs.netbsd.org -maproot=0 -ro
	/ -alldirs -maproot=0 horn 
	/usr -alldirs -maproot=0 horn 
	/cdrom -alldirs -maproot=0 -ro 
	/zip -root=0 asim

	With the folloing filesystems mounted:
	armandeche# df -l
	Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
	/dev/wd0a       99124    42519    51648    45%    /
	/dev/wd0e      594368   412601   152048    73%    /usr
	/dev/wd0f     5317498  4126413  1084735    79%    /home
	mfs:178         14487      103    13659     0%    /tmp
	/dev/cd0a      237890   237890        0   100%    /cdrom

	When mountd is started export list is correct:
	Exports list on localhost:
	/usr                               horn 
	/home/cvs.netbsd.org               Everyone
	/cdrom                             Everyone
	/                                  horn 
	/zip                               asim.lip6.fr 

	But if I kill -HUP mountd (without changes to /etc/exports or the
	mounted filesystems), then I have:
	Exports list on localhost:
	/usr                               horn 
	/                                  horn 
	/zip                               asim.lip6.fr 

	and in messages:
	Dec 22 02:50:01 armandeche mountd[6599]: "/home/cvs.netbsd.org -maproot", line 1: Can't change attributes for /home/cvs.netbsd.org to Default
	Dec 22 02:50:01 armandeche mountd[6599]: "/cdrom -alldirs -maproot", line 4: Can't change attributes for /cdrom to Default

	If I kill and restart mountd the export list is correct again

	If I export /home instead of /home/cvs.netbsd.org I don't have this
	problem.

	It seems that the change in mountd.c 1.57->1.58 doesn't work
	when the exported point is not a filesystem root. I didn't look
	further yet.
