I am at a strange text console, 260*67 characters, newcons in FreeBSD-current 
amd64, having come back from X, and seem to get blank lines in between, 
double-spacing.

Here is my /etc/fstab from NetBSD 6.1-STABLE on 8 GB Kingston Data Traveler:

# NetBSD /targetroot/etc/fstab
# See /usr/share/examples/fstab/ for more examples.
/dev/sd0a               /       ffs     rw,log           1 1
/dev/sd0b               none    swap    sw,dp            0 0
kernfs          /kern   kernfs  rw
ptyfs           /dev/pts        ptyfs   rw
procfs          /proc   procfs  rw
/dev/cd0a               /cdrom  cd9660  ro,noauto

Problem is I don't always know if USB stick will be /dev/sd0, and an internal 
media reader can play further havoc with device numbers.

NetBSD-current with NAME= gets around that problem.

What do you do for /etc/fstab?
