Discuss: Workstation with Read-Only access for users (Protected)
Dear list,
as opposed to Windows installations, I am glad needing no hardware protection
to secure the dual boot Skolelinux installation.
On the other hand, I observe cases where the non-protection shows
disadvantages: Especially in school labs, it happens that machines are turned
off during booting or running. In these cases, the Linux installation can run
into trouble - at least ckdsk is necessary.
I am quite sure that it whould be possible to mount /usr and /boot ro.
As logs go to tjener, even /etc and /var could be kept non-writable.
Another approach would clone the technique of Protector hardware, simulating a
transparent layer on the hard disk that will be gone after reboot. Same thing
is used by unionfs: Knoppix makes CD-ROM partition seemingly writable by
merging in a RAM-Disk.
I believe if we find a simple (KISS!) way to implement a mostly r-o
Workstation, this would be much more robust in school settings.
What do you think?
Usefull? Feasable?
Regards
Ralf
One step beyond: Suspend running KDM to disk, and start from a frozen copy
within no-time for any further boot...
