Subject: build-sys: require libmount >= 2.30 (#6795)
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=af2805e1412d56970eb1e735fe8dc954e572aa1c;p=elogind.git

build-sys: require libmount >= 2.30 (#6795)

Fixes #4871.

The new libmount has two changes relevant for us:

- x-* options are propagated to /run/mount/utab and are visible through
  libmount (fixes #4817).

- umount -c now really works (partially solves #6115).
