Aha..

vega:/home/jws# mount
/dev/hda5 on / type ext2 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,nodev)
/dev/hda6 on /dosd type vfat (rw,noexec,nosuid,nodev,umask=000)
automount(pid2284) on /misc type autofs
(rw,fd=4,pgrp=2284,minproto=2,maxproto=4)
rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

There doesn't seem to be a filesystem actually called tmpfs but
there is devshm which has the "type" tmpfs.

Is this a clue? Maybe I should make some link. I wonder what
tricks were performed by my latest Debian dist-upgrade.

For completeness, here is /etc/fstab:

# /etc/fstab: static file system information.
#
# <file system><mount point><type><options>      <dump><pass>
/dev/hda5      /        ext2  defaults,errors=remount-ro  0 1
/dev/hda6      /dosd    vfat  defaults,rw,user,umask=000  0 0
/dev/hda7      none     swap  sw                          0 0
proc           /proc    proc  defaults                    0 0
/dev/fd0       /floppy  auto  defaults,user,noauto        0 0
/dev/hdc       /cdrom   iso9660 defaults,ro,user,noauto   0 0
/dev/hdd       /cdrw    iso9660 defaults,user,noauto      0 0
procyon:/      /nfs     nfs   defaults,noauto,rw          0 0

There is no tmpfs, but there never was, and dosemu always worked
(until today).
