Ah, that may reduce my interest in UML before the book even arrives :-)
I was hooked by the promise of UML sharing the host's o/s image, but
that uses Copy-on-Write ... so I'm unclear whether local changes in the
child will be visible to the host.

Yeah, on Sol10:
root at dooku:/var/zones # ls listserv/*
arp        dtrace     null       rdsk       syscon     ticlts     zconsole
conslog    dtremote   openprom   rmt        sysevent   ticots     zero
console    fd         poll       sad        sysmsg     ticotsord
cpu        kstat      pool       stderr     systty     tty
crypto     log        ptmx       stdin      tcp        udp
cryptoadm  logindmux  pts        stdout     tcp6       udp6
dsk        msglog     random     swap       term       urandom

backup    etc       lib       opt       sbin      usr
bin       export    mnt       platform  system    var
dev       home      net       proc      tmp

Time to look at linux-vserver! 

Thank you for the lead.
