Re: [9fans] Fossil robustness

[John Soros <sorosj@gmail.com>]

Yes, i've had a lot of problems with fossil when it gets killed. My issue was
with wikifs that had some sort of memory leak i suspect, it would fill up the
memory, and then fossil would crash and/or get corrupted. I had an idea for a
project to use mycroftiv's rootless kernel images and have a script check
whether fossil died or what, and if it did reformat it using latest venti
snapshot and reopen the root, but i don't know how involved that would be.
 I would think -r doesn't modify the filesystem if snapshotting is turned off,
but i am probably the wrong person to be asked...I currently don't even have
my plan9 system installed.
