Hmm. Okay. df -k tells me this:

Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/ram0                16208      4456     11752  27% /
/dev/ram1                 2022        47      1975   2% /var/log

and free tells me this:

         total:    used:    free:  shared: buffers:  cached:
Mem:  15007744 14741504   266240  6922240  6479872  2195456
Swap:        0        0        0
MemTotal:     14656 kB
MemFree:        260 kB
MemShared:     6760 kB

SwapTotal:        0 kB

I guess I could cut ram0 down by half and still have plenty of room. Is 
that reasonable?
