Subject: xfs_scrub_fail: fix sendmail detection
X-Git-Tag: v6.6.0~2^2~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=83535ee5c9e3f040258d6d7456c8b5504fb6e6f5;p=thirdparty%2Fxfsprogs-dev.git

xfs_scrub_fail: fix sendmail detection

This script emails the results of failed scrub runs to root.  We
shouldn't be hardcoding the path to the mailer program because distros
can change the path according to their whim.  Modify this script to use
command -v to find the program.
