Hi all
Is it possible somehow for me to make my normal Linux root filesystem
a read only filesystem.
I mean even for root too.
I anticipate a question being asked in reply ,why do i want this? :-)
So this is not because i want it but when i installed FC 5 test 2 , i
was not able to boot as it said there is no inittab file strangely.
So this means i have to create it ,manually but then it couldnt mount
the root partition in single user mode, saying it is already mounted
or in use.
Then i copied inittab from my other installation to the /etc of FC5
and i could boot but surprisingly it acepted whatever i entered as
root's passwd. :(
i thought i did something wrong ( which i think i did perhaps ), so
tried creating a file but then it said filesystem is readonly.
Also i formatted my root partition as reiserFS partition.
Later when i reinstalled with ext3 option everything went fine .
but still this gave inquisity of my original question.
Can i make my installed rootFS a readonly FS for everybody?
TIA

Well, I didn't understand half what you did, but answering to your question:
YES, you can mount any partition as read only. In particular, in
embedded projects we usually use CRAMFS, because besides being read
only, it compacts the file system with a nice 40% ratio. (see mkfs.cramfs)
I don't know if that's what you want for your workstation, but it's the
answer to your question. Hope it can help you out.
