 |
|
Hi all.
I've recently setup a 4TB disk with two partitions, one of which I want to encrypt. I'm runnign Xfce and udisks manages mounts/unmounts. My system is running with udev until now:
| emerge -avq1 udisks: | [ebuild N ] sys-fs/eudev-3.1.5 USE="hwdb kmod static-libs -introspection -rule-generator (-selinux) {-test}" ABI_X86="(64) -32 (-x32)"
[ebuild U ] sys-fs/lvm2-2.02.136 [2.02.116] USE="readline static thin udev* -clvm -cman -device-mapper-only -lvm1 -lvm2create_initrd (-selinux) -static-libs -systemd"
[ebuild R ] sys-fs/udisks-2.1.4 USE="cryptsetup* gptfdisk -debug -introspection (-selinux) -systemd"
[blocks B ] sys-fs/udev ("sys-fs/udev" is blocking sys-fs/eudev-3.1.5) |
The back story is that encrypted block devices appear with a lock emblem on Xfce desktop. When I click the locked desktop item I am prompted with a pass-phrase dialogue box and I can type my pass-phrase, okay. But then I'm immediately prompted with an error message saying there's no filesystem available. So I assumed that was due to udisks being compiled *without* cryptsetup USE flag. I could do without the GUI stuff but I'm still curious about using it.
I hadn't selected cryptsetup before since I have never used encryption so far. So I guess I must remove udev and install eudev, right?
This is a major change, so do I have anything to care about beforehand? (let alone making a backup, which I already did.)

IIRC I need LVM2 with static USE flag if I want an initramfs. This dates a couple of years ago, I believe. Is it still true?

VinzC,
Yes and no. LVM2 with static USE flag is the traditional way of doing it.
Dynamically linked LVM2, with all its bits works too.

Thanks, NeddySeagoon. I've taken a look at the wiki and it says that the static flag *can* be enabled:
| Gentoo Wiki wrote: | | The static USE flag may also be enabled on the package sys-fs/lvm2 so that genkernel will use the system binaries (otherwise it will build its own private copy). |
Kind of looks safe. What consequence will that have on the initramfs? — it's currently about 4.5MB as I have two bootsplash screens embedded. So I suppose I can keep udev after I have removed the static USE flag from lvm2?
