Subject: fix(dracut.sh): kmoddir does not handle trailing /
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ddcb137ea2a4d79491ff94f1f7802dcaa7ac381;p=thirdparty%2Fdracut.git

fix(dracut.sh): kmoddir does not handle trailing /

Fixes https://github.com/dracutdevs/dracut/issues/2236

+(/) only works in bash interactive mode. Using any non-interactive
bash run simply doesn't remove anything.

The solution is copied from dracut-lib.sh, trim().
