Subject: discover/yaboot-parser: Handle 'partition=' directive override
X-Git-Tag: v1.0.0~504
X-Git-Url: https://git.ozlabs.org/?p=petitboot;a=commitdiff_plain;h=503d1454f222e2b0c6f8dd433a9e91870a17f460;hp=503d1454f222e2b0c6f8dd433a9e91870a17f460

discover/yaboot-parser: Handle 'partition=' directive override

In a yaboot conf file, we may see a device= directive that actually
specifies a partition (eg, sda1) rather than the underlying block device
(sda). If we then encounter a partition= directive, we don't handle the
resolution of the partition correctly, as we simply append the
partition number to the device= string.

This change implements a smarter handling of the partition= directive,
where we strip away any partition information from the device=
parameter first.
