Subject: [OpenWrt-Devel] [PATCH] base-files: implement new config
"root_readonly" (RESENT)
Message-ID:<[email protected]>
Content-Type: text/plain; charset="utf-8"; Format="flowed"
In the view of user, we always hard power-off router, and do not expect
any unexpected background flashing which can lead to fs corruption.
As the number of package of OpenWRT increases, the probability of
unexpected background flashing will increase.
Although OpenWRT developers are brilliant and hard-working, it is
impossible to guarantee all packages are bug-free.
This change try to implement a new config "root_readonly" in
/etc/config/system, which will remount root to read only when reading
system config during boot process. This should prevent background flashing.
root_readonly=0 #0 - root will be read-write, 1 - root will be read-only
Assumption
1. Early boot process do not trigger unnecessary flashing
2. default setting=0 (read-write) to preserve backward compatibility
3. user know how to remount root rw manually if he/she set this option
