Subject: Add tests for index --no-check-device, and support for t/mnt.
X-Git-Tag: bup-0.25-rc2~34
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=bup.git;a=commitdiff_plain;h=8622b8cccd80979d8fb10831b9f66be621e70de9

Add tests for index --no-check-device, and support for t/mnt.

Add support for t/mnt; anything mounted there will be cleaned up
during "make clean".

Thanks to Zak Wilcox <iwilcox@iwilcox.me.uk> for an earlier version of
these tests.
