Description DEMAINE Benoît-Pierre, aka DoubleHP 2010-01-13 14:50:49 UTC 
I am installing a fresh AMD64; during genkernel:

Comment 1 DEMAINE Benoît-Pierre, aka DoubleHP 2010-01-13 15:06:27 UTC 
and sys-fs/multipath-tools
Comment 2 Rafał Mużyło 2010-01-13 15:39:53 UTC 
And just what depends on that broken lib ?
Comment 3 DEMAINE Benoît-Pierre, aka DoubleHP 2010-01-13 15:43:42 UTC 
Genkernel when multipath is required during install.
Comment 4 Rafał Mużyło 2010-01-13 18:45:02 UTC 
OK, I see a few problems here:
- ~sys-fs/multipath-tools-0.4.8 ebuilds are probably lying: 
according to git log, it no longer uses libsysfs
- libsysfs is broken (see bug 220347), especially given that recent udev
demands CONFIG_SYSFS_DEPRECATED_V2 unset
- I don't see a dep on sys-fs/multipath-tools in genkernel
Comment 5 DEMAINE Benoît-Pierre, aka DoubleHP 2010-01-13 18:48:47 UTC 
multipath support is optionnal in /etc/genkernel.conf . So a standard dep may be "toomuch".

creating a USE flag seems a better idea to me: pu the flag ON, and make genkernel sensible to it, and if ON, then make conditionnal dep ...

I see this message at boot, and udev also asks me to disable SYSFS_DEPRECATED in my kernel; i did not find yet the entry in make menuconfig to disable it ...
Comment 6 DEMAINE Benoît-Pierre, aka DoubleHP 2010-01-13 18:50:47 UTC 
note: i am not multipath expert, but i was said it could help in my case, so, I try to use it. And it is obviously quiet hard. More deps than those I reported may be required.

But it seams a "standard" option/feature for the kernel, and support for it should be a bit more easy/trivial. Ideally:

USE="multipath" emerge genkernel
should do everything IMHO.
Comment 7 Rafał Mużyło 2010-01-13 19:55:29 UTC 
Use search feature of menuconfig.
It's in "General setup".
Comment 8 Andrew Gaffney (RETIRED) gentoo-dev 2010-01-14 03:12:07 UTC 
The multipath support in genkernel is still experimental. It's not entirely expected to work.
Comment 9 Samuli Suominen (RETIRED) gentoo-dev 2011-08-06 08:25:42 UTC 
Feel free to remove any sysfsutils requiring code from genkernel with regard to bug 377709.
