console goes to serial as well, so this doesn't stop garbage from going
to serial. But it creates garbage itself.

OVMF now supports booting from disks.

Use it to add custom files, so that tests which need them work.

This disables progress indicator for tests. This in turn fixes test
flakiness as they ended up timing-dependent.

Skip test if parted is unavailable instead of returning false failure.

Given special semantics of ZFS it's far from clear what the expected
result is. Just skip it for now

LVM miscalculates bitmap size with small extent, so start with 16K as
for other RAID types.

Until version 2.02.103 LVM counts metadata segments twice when checking
available space, reduce segment count by one to account for this bug.

LVM mirror defaults to RAID1 today and can be different on different
systems as set in lvm.conf.

Write activity with LVM/RAID can happen after filesystem is unmounted.
In my testing modification time of loop files was 15 - 20 seconds
after unmount.  So use time as close to unmount as possible as
reference instead.

Fixes the language tests is no make install was done.

This fixes bug that system would become unbootable after ext*
online resize if no resize_inode was created at ext* format time.

abs_top_srcdir appeared in Autoconf 2.52f. Minimal grub requirement
is 2.60 so we should be good here.

This requires access to files in both host and grub image, so
implementing as separate test unit instead of script test was
more easy.

Tests file access with all filters enabled. It does it both for local
and network access, due to regression in signature checking over network.

This includes all files in distribution to not depend on existence
of compression tools and gpg. Test preloads all required modules to
avoid having to provide signatures for them.

Still not implemented is file offset filter (is not available in grub
script, needs extra module)

This allows running tests that require extra files using netboot as well.

Copying the themes directory in grub-shell isn't
parallel-test-friendly and breaks on the second test when the source
directory is read-only (as in "make distcheck").  Instead, add a
hidden --themes-directory option to grub-mkrescue et al, and use it
in grub-shell.

than hardcoding /usr/local/bin/xorriso.

	quite some time locally. Most of the test require root so they are
	skipped when run without necessarry privelegies.
