Subject: d/shuffle-boot-files: make it POSIX compliant
X-Git-Tag: archive/raspbian/4.14.1+11-gb0b734a8b3-1+rpi1^2~48
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=353140bef3860e270830833e40c9bb24f891a931;p=xen.git

d/shuffle-boot-files: make it POSIX compliant

We want to use sh instead of bash for this program, so we have to get
rid of the back ticks and the ${//} substitution, which is a bash
extension.

Based on a patch by Elliott Mitchell.
