Subject: lsblk: don't ask udev when --sysroot specified
X-Git-Tag: v2.33-rc1~26
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=137599ebe152ae10ff6fa492956a65f173623f04;p=thirdparty%2Futil-linux.git

lsblk: don't ask udev when --sysroot specified

We use --sysroot to get information about block devices from /proc and
/sys dumps. In this case does not make sense to read anything from
udev as udevd is about the current system devices.
