As terry knows of course, the Interjet
had the following /etc/symlinks: (excuse linewrap)
lrwxrwxrwx  1 root   wheel         20 Mr 28  2001 crontab@ ->
/writable/system/crontab
lrwxrwxrwx  1 root   wheel         18 Mr 28  2001 group@ ->
/writable/system/group
lrwxrwxrwx  1 root   wheel         22 Mr 28  2001 localtime@ ->
/writable/system/localtime
lrwxrwxrwx  1 root   wheel          3 Mr 28  2001 malloc.conf@ -> >>A
lrwxrwxrwx  1 root   wheel         26 Mr 28  2001 master.passwd@ ->
/writable/system/master.passwd
lrwxrwxrwx  1 root   wheel         19 Mr 28  2001 pwd.db@ ->
/writable/system/pwd.db
lrwxrwxrwx  1 root   wheel         28 Mr 28  2001 resolv.conf@ ->

lrwxrwxrwx  1 root   wheel         31 Mr 28  2001 sendmail.cf@ ->

lrwxrwxrwx  1 root   wheel         20 Mr 28  2001 spwd.db@ ->

the single root+usr partition is mounted read-only.
