Re: Bug#595790: hostid: useless unless fixed

When you create a ZFS pool the value of the hostid is stored inside it.
When the system is going to import a pool it checks if the hostid stored
inside the pool matches the current host hostid. If it don't matches it
refuses to import the pool.

Not suprising: sunos is one of those legacy systems where old scripts tend to assume hostid is a system serial number. :)

We are working on packaging ZoL (ZFS on Linux native with DKMS) [1] for
Debian and we are checking how we can solve this issue.

I'd suggest an application-specific UUID incorporating the hostname.
