Re: [Xen-users] Please advise re 'on_crash' parameter.

[Steve Wray <steve.wray@xxxxxxxxx>]

Ok well given the lack of any further feedback on this issue, I have to ask 
is this 'on_crash' thing even officially supported in Xen?

Please remember that an email is just like a postcard; it is not 
confidential nor private nor secure and can be read by many other people 
than the intended recipient. A postcard can be read by anyone at the mail 
sorting office and expecting what is written on it to be private and secret 
is not realistic. Please hold no higher expectation of email.
If you need to send confidential information in an email you need to use 
encryption. PGP is Pretty good for this.
