I have wondered about how to set up a system with a read only / and /usr partition, but as you say things like mount wanting to write into /etc really spoil the idea. Does anyone have a list of issues that stop / and /usr being mounted read only (either logically or physically, or on read only media) on a machine running say Solaris ? I'll start off the list with the following.
I'd also include: (some of these are Sol 2.x specific)
Program/system writes to mountd /etc/mnttab
/etc/rmtab and /etc/.mnttab.lock
automountd /etc/mnttab passwd /etc/passwd /etc/shadow
/etc/opasswd /etc/oshadow
syslogd /etc/syslog.pid crond /etc/cron.d/FIFO opie /etc/opiekeys
skey /etc/skeykeys ... depends on skey config
sendmail /etc/mail/aliases .. if you update your aliases here lp /etc/lp/..... updates for warning/status messages etc init /etc/initpipe utmpd /etc/utmppipe also, /etc/inet/hosts, /etc/group, and /etc/dfs/* would probably be modified on a lot of systems.....one of the default startup scripts in Sol 2.x writes to /etc/dfs/sharetab.. About /dev, /devices - some of Sun's startup scripts chmod these on startup. Also, there would be problems with a lot of other devices, not to mention pseudo ttys, hard disks, and almost as important, /dev/audio* :) Dave ---------------------------------------------------------------------------- Dave Matthews Senior Programmer email: dm () alphasun anu edu au School of Mathematical Sciences phone: (06) 249 3833, int. +61 6 249 3833 Australian National University fax: (06) 249 5549, int. +61 6 249 5549 CANBERRA ACT 0200 ----------------------------------------------------------------------------
