Subject: Strip comments from checksums files passed to "shaXsum -c"
X-Git-Tag: debian/1%20180328~22
X-Git-Url: http://git.grml.org/?p=live-boot-grml.git;a=commitdiff_plain;h=3afe60c1aaea1f12a37d6b810064c59fe87e8078

Strip comments from checksums files passed to "shaXsum -c"

As reported in #796474, the busybox implementation of the various
shaXsum command fails when it encounters comment lines that it
can't parse. This fixes the 'verify-checksums' boot parameter.

Thanks: Andreas Heinlein for the report
Closes: #856482
