Description:   Opened: 2007-03-25 13:52 0000 
/sbin/lilo from sys-boot/lilo-22.8 outputs the following error message:

# lilo
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
Added Linux *
[...]

sys-fs/device-mapper-1.02.12 is installed on the system (not needed, but gets
pulled by dependencies of sys-apps/hal -> sys-fs/cryptsetup-luks), but the
kernel is configured without multi-device support (CONFIG_MD).

Lilo does not display the error message anymore after the following sequence of
commands:
# emerge -C device-mapper
# emerge lilo
# emerge device-mapper

Maybe it would be more appropriate to control this via a USE flag?

Proposed changes for lilo-22.8.ebuild

Attached changes for lilo-22.8.ebuild work for me.
An "lvm2" local USE flag would already exist.

We use diffs over sed statements as they do not break silently when they no
longer apply. I will commit this on monday (even though I feel that the bug is
in the HAL dependencies).
I do not have access to non-production X86 hardware before monday. However, if
you can rework this into a proper .diff, talk to me on IRC.

lilo-22.8-nodevmapper.patch

Attached patch should be applied if the lvm2 USE flag is unset.

Alternatively, one could pass "HDM= DEVMAPPER=" to emake in that case.

Fixed in -r1.
