>Description:
Using "puffs" on a system running a modular kernel doesn't work ...

tron@lyssa:~tron#mount -t smbfs -o rump tmpfs /mnt                             
rump_smbfs is work-in-progress.  forcing debug mode
rump_smbfs: no server name specified
rump_smbfs: resolve 22: No such file or directory
tron@lyssa:~tron#mount -t tmpfs -o rump tmpfs /mnt
rump_tmpfs: puffs_mount: cannot open /dev/puffs
rump_tmpfs: puffs_daemon: Device not configured
tron@lyssa:~tron#assertion "n == 4" failed: file 
"/src/NetBSD-current/src/lib/libpuffs/puffs.c", line 474, function "shutdaemon"

... unless you manually load the "puffs" module:

tron@lyssa:~tron#modload puffs
tron@lyssa:~tron#mount -t tmpfs -o rump tmpfs /mnt
tron@lyssa:~tron#df

>How-To-Repeat:
1.) Boot a modular kernel.
2.) Run "mount -t smbfs -o rump tmpfs /mnt".

Not known.
