Re: [gentoo-user] DHCP - specific inet no - how to
Hello, Normally, a device tries to get the previous inet number, but sometime this changes. DHCP clients can neither request nor suggest a specific IP address, so they don't try to get anything. It's just the DHCP server giving out the previous IP to the same client, either by chance or because the existing lease hasn't expired yet. But I cannot configure the DHCP server myself since this is provided by my internet provider. Then you're basically out of luck. Since you have few devices and those devices are under your control, just forget about DHCP and configure them statically. andrea

[gentoo-user] More file system frustration
If I try and do: moriah ~ # mount -t ceph 192.168.44.68:6789:/ /mnt/ceph -o users mount error 22 = Invalid argument It turns out the driver doesnt recognise the user or users mount option and gentoo wont let a user mount or access a root mount, or even let a user mount. Tried adding the user to the disk group without any effect. Something in gentoo's user access control is causing this problem I think, so how can I get around it? BillK

Re: [gentoo-user] genkernel compile only one new module
make was specifically designed so that by default, it would only compile things whose dependencies had changed since last run. If your kernel config had not selected the object before, and all you do is add it as a module, then when you rerun make, only that module should be recompiled. However if you do built-in to module or vice versa, you're out of luck. On Nov 9, 2012 12:58 AM, ifj. Stefán István iste...@stef.hu wrote: Hello!
