HD Install :: Read-Only Compact Flash

I am building a diskless network client;
I would like to restrict changes to DSL after (re-mastering)
I've also discovered compact flash cards are limited to about 100,000 erase/write cycles before they fail.

Is it possible to get a read-only compact flash reader?
Or are there any other solutions?

Thanks in advance

Use a frugal installation for your compact flash.

I have a similar question.

I know that Frugal uses up less disk but it's still installed Read-Write. I want to be able to pull the power plug and not worry about fsck failing on a reboot. Can't I mount root as 'ro'?

I thought the frugal cf type installation scripts would install it so that it would not be rw...

In any case, just remove the "frugal" boot/cheatcode from your bootloader, and /cdrom should now be mounted as RO.

Thanks for the suggestion ^thehatsrule^ but removing the frugal switch didn't seem to help. I am running off an HD install so maybe that's why. Do I need to turn on initrd or something else to do with a ramdisk? I know that there are certain system files that need to be writeable.

It looks like I may need to use tmpfs or upgrade to DSL 3.0 so I can use unionfs. Does anyone have any experience with this? I'll give this a try on friday.
