Hey-
I'm looking at the docs for CMU's cygnus IMAP server, and came across the following warning in a README:
8. LINUX SYSTEMS ONLY: Set the configuration, user, quota, and partition directories to update synchronously. Failure to do this may lead to data corruption and/or loss of mail after a system crash.
cd /var/imap /sbin/chattr +S . user quota /sbin/chattr +S /var/spool/imap
Also set the queue directory of the mail daemon to update synchronously. The following example is for sendmail:
/sbin/chattr +S /var/spool/mqueue
What is the reason for this? Won't this hurt performance on a well loaded system? Also, the notes mention that they only used Linux 1.2.13-- is this something that is no longer necessary with that later 1.3.x kernels? (I have 1.3.70) Basically, what is this all about, and what's wrong with Linux that it's necessary?
Thanks,
