like a ubirmvol ... --i-know-what-im-doing.
Sorry for the delay reply, caused by my holiday.
True, enforcement doesn't need to happen in kernel (though I think it's
nicer, but really just a matter of taste, I guess). ubi-tools would still
need to be able to recognize critical volumes somehow, and that could be
done by checking if the 'volume-is-critical' property is present in
/sys/class/ubi/ubi*_*/of_node/
Exactly.
I also don't mind adding a in-memory 'volume-is-critical' property to
UBI directly. I'm just a little hesitated to change the UAPI or the on-disk
data structures for this features.
Add a new interface under the sysfs is fine.
If you prefer going down that road instead I will work on patches for
git.infradead.org/mtd-utils.git instead.
Yes. When done in userspace, it's also much easier to offer the --i-know-what-im-doing
flag to still remove a critical volume.
Looks good, I like it.
