I was a little too "enthusiastic", sorry.

I thought like you, but:
 - "cgroupfs-mount" was developed in such a way that it does nothing
when it detects that another initializer is at work (fstab way
included).
 - It was added as a dependency of "liblxc1", not a recommend.
But no problems, it will work fine.

Otherwise, to be perfectly clean, what do you think of adding
"cgroupfs-mount" in recommends (or dependencies if in "required") on
"lxc" package ?

Thanks,

Bug#798237: isc-dhcp-server: Support for ddns-update-style not compiled in

[Thibaut Cheze]

Hi,

The server starts without the parameter or if set to 'none'.
With values 'standard' or 'interim', server doesn't start and print out:

Maybe this problem is linked with "Disable NSUPDATE (closes: #712503)" in 
changelog for version 4.3.3-2.

Best regards,
