[GTALUG] war story: power failure makes CentOS system unbootable

| Hmm, it's more complicated than that.  vfat supports atime updates,

| a simple fix.

Interesting.  I never knew that.

But the dirty bit could/should be cleared whenever the FS is in a 
consistent state.  Like: after a sync AND no files are open.  Maybe having 
a process with a working directory on the FS counts as having a file 
open; maybe not.

| Can you somehow flag it to be mounted read-only and then manually remount
| it if you actually have a reason to update it?

I imagine that that would require cooperation of too many actors (each 
thinking they are the star of the show).  I could experiment but how could 
I test all the cases>

My initial position was: packagekit should not need to access the ESP
except to apply updates.  But packagekit accesses the ESP when it
starts up.
