[ale] Shutdown process

[ChrisF at computone.com (Chris Fowler)]

Why can I not run a filesystem in RO mode and not worry about the user powering it off??? The use will never shutdown the device properly.?? I just need files on the FS to load programs in memory.?? 

I believed that if I just remounted the FS in RO mode, that would take care of the dirty FS problem.?? Am I mistaken?


Can I do the following:


1. Load kernel
2. Mount / in RO
3. remount in RW for loading and configuraiton and storage of settings
4. remount in RO so user can take control.
5. Users turns power off when finised.


Plese understand I do not plan to use SysVInit,?? I am going to create a basic init to take care of a few things.?? If I have to use SysVInit package, I will but it just adds too much bulk to the package.?? I really am not concerned with users and permissions.?? My main goal is to use the linux kernel and the filesystem and programs that run under the linux kernel. I don't need the whold package such as RH 7, etc.?? I do not want damage to the FS though.

Chris

Does this return successfully??? Unless you've done something special
to your file system, you typically can't remount it read-only.?? There
are files that are open for writing like /var/run/utmp.


I would recommend using reiserfs and just powering down after a sync.
