Subject: Ignore ramdisk devices.
X-Git-Tag: v0.0.1~14
X-Git-Url: https://git.ozlabs.org/?p=petitboot;a=commitdiff_plain;h=167387fd92cc204a38bc0afa75b66889dec3decf;hp=eff968df2ac394b4ebbef0ad6f91d833ca0f22b6

Ignore ramdisk devices.

Don't try and parse the config from ramdisk devices, and add a general
system for device ignoring.
