I have not been able to test this because each time I try, I get
"Multiple devices on your system are labelled /." [Exit Installer]
even though really, truly, and honestly only one device is labeled
"/"
If this looks reasonably safe, maybe it can get tossed into the mix
and I'll try the upgrade another day....
All it does is mark it with the "test_fs" flag (which won't be needed
when ext4 goes "live") and then as long as the ext3 fs is mounted as
ext4 during install, every file which is created/updated/installed
will be in the new extents format.
Thanks,
