http://askubuntu.com/questions/165614/i ... und-folderSomeone on that thread got this message from cron:
Some local file systems lack a lost+found directory. This means if the
file system is damaged and needs to be repaired, fsck will not have
anywhere to put stray files for recovery. You should consider creating
a lost+found directory with mklost+found(8).
I guess I've been lucky - I've deleted the lost+found folder on my separate /home partitions for awhile and haven't had a problem. In fact, I don't think I've seen anything in lost+found since I switched from using ext2 to ext3 for my installations. (more than 10 years ago.)
Your solution seems like a good one - leave it alone if it's there. It's on the TODO list for the tools.
Uh, why would it exist on a live-CD image?
Another issue with the installer: PermitRootLogin in sshd_config is now handled differently in Debian. Instead of "yes" it's set to "without-password" which does not mean what you think it means. The default setting allows root to login through ssh only with auth keys.
I haven't decided what to do about that. I've been thinking about removing or disabling openssh-server for awhile. If that's the case, I could remove the relevant code from the installer and snapshot. AFAIK, most live distros don't have ssh running. Or I could leave it in and add the new option to the scripts and config files.
