Bug 48243 – sys-boot/lilo-22.5.8-r2 has unneeded dep of device-mapper-1.00.08 - ~arch

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description solar (RETIRED) 2004-04-18 11:00:14 UTC]

Hey it appears your recent changes to ~x86 lilo have messed up my system
deps (thus breaking my 'world' ;/) and is trying to force me to patch the
kernel for support I could care less about. I use vanilla/grsec-2.4.x
and I'm not keen on having to patch my kernel sources just because
device-mapper exists.

Now from reading the ebuild it looks like you could tie this support 
into an existing USE flag vs forcing it on *

portage/profiles/use.local.desc:sys-kernel/gentoo-sources:evms2 - adds EVMS 2.0 support drop EVMS 1.2.1

# devmapper-patch (boot on evms/lvm2)        

Maybe you could change it to something like.

IUSE=evms2
....

DEPEND=">=sys-apps/sed-4
        dev-lang/nasm
        >=sys-devel/bin86-0.15.5
        evms2? ( >=sys-libs/device-mapper-1.00.08 )"

....
src_unpack() {
...
   cd ${S};
   use evms2 && epatch ${FILESDIR}/${P}-devmapper_gentoo.patch


I've tested and it appears to work just fine and should meet the needs
of everybody..

Note: 
I don't know if you would want evms or evms2. I just called it evms2 so I could continue building world.

[Comment 2 Thomas Raschbacher 2004-04-21 06:49:40 UTC]

well .. it's needed for lvm too and ppl who use lvm won't neccesarily have evms(2) in their USE ..

new USE-flag for device-mapper maybe? does that make sense?

regards

Sure anything makes sense and long as device-mapper is not forced on us.
Might want to shorten it's name up (your call).. USE=devmap maybe

I second this. lilo is haunting my `emerge -Upv world` for several weeks now and I am *NOT* going to patch my vanilla 2.4 kernel just for that.

Created attachment 30780 [details]
An ebuild file for lilo-22.5.8

This ebuild makes the use of device-mapper optional ("devmap" USE flag, devs:
change the flag name as you see fit).

Message informing about this is also displayed before emerge begins (from
src_unpack() ).

Created attachment 30781 [details, diff]
A patch for -r3 ebuild

diffed against -r2

[Comment 7 Thomas Raschbacher 2004-05-09 13:58:40 UTC]

added as -r3 

[Comment 8 Christophe Saout 2004-05-10 09:46:48 UTC]

The -r3 ebuild is broken, you need to write

 devmap? ( >=sys-libs/device-mapper-1.00.08 )"

instead of

 devmap? (>=sys-libs/device-mapper-1.00.08)"

(with additional whitespace)

[Comment 9 Christophe Saout 2004-05-10 10:02:59 UTC]

And, by the way:

Building lilo against libdevmapper does not require the kernel to have device-mapper.

(PS: I want to be able to reopen bugs... *sigh*)
