Subject: mount: avoid duplicates for root fs in mtab
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=309fd2e79370be77c192ec272657aef9a5320ffb;p=util-linux

mount: avoid duplicates for root fs in mtab

If the root fs is defined with LABEL or UUID in fstab, avoid
a duplicate entry in mtab when calling mount without existing
mtab.
A mount -f / creates two entries, one for LABEL and another
for the devicename, because canonicalize does not expand the
LABEL or UUID tags.
