nbd? ( sys-libs/libnbd )

[Comment 3 Arniii 2024-08-23 14:38:39 UTC]

it seems more like USE flag `nbd` doesn't propagate.

[Comment 4 Mike Gilbert 2024-08-23 15:33:24 UTC]

Seems that libvirt has a direct dependency on libnbd which is not expressed in the ebuild.

Shouldn't it be something like this? :

nbd? (sys-block/nbdkit[nbd] ) 

because sys-block/nbdkit[nbd] has dependency to sys-lib/libnbd

in the pull request I see next:

nbd? (
		sys-block/nbdkit
		sys-libs/libnbd
	)

    app-emulation/libvirt: Depend on sys-libs/libnbd too
    
    In its upstream commit of v9.8.0-rc1~27 [1] libvirt introduced an
    optional dependency on libnbd. Reflect this in corresponding
    ebuilds. Now, pre-10.0.0 ebuilds do not have nbd USE flag. Thus,
    it needs to be introduced to record the dependency properly.
    NB, initially, the configure option was named 'libnbd' and only
    after v9.9.0-rc1~108 [2] it was changed to 'nbdkit'. Hence the
    discrepancy in libvirt-9.8.0-r3 and libvirt-9.9.0-r3 ebuilds.
