Running `make check` on a virtual machine at 1und1.de is
failing for 5 tests:

FAIL: misc/nproc-avail

++ nproc --all
+ all=4
++ nproc
+ available=8
+ test 8 -le 4
+ fail=1

I added an strace for both runs.

FAIL: tail-2/wait

+ test '!' -r unreadable
+ timeout 1 tail -s0.1 -F ---disable-inotify unreadable
tail: cannot open `unreadable' for reading: Permission denied
+ test 124 = 124
+ timeout 1 tail -s0.1 -F ---disable-inotify not_here
tail: cannot open `not_here' for reading: No such file or directory
+ test 124 = 124
+ grep -Ev 'inotify (resources exhausted|cannot be used)' tail.err
+ mv x tail.err
+ test -s tail.err
+ fail=1

Do you need an strace output here?

FAIL: ls/stat-dtype

+ ls --file-type d
ls: cannot access d/s: Permission denied

I added an strace log.
The same test succeeds if run as root.

FAIL: ls/stat-free-color

+ n_stat=7
+ case $n_stat in
+ fail=1

FAIL: tail-2/follow-stdin

+ timeout 1 tail -f
+ test 124 = 124
+ test -s err
+ fail=1

Unfortunately, I don't know what virtualisation software they
are using, but as it is a mass hoster, I guess they have their own
kernel patches etc.

Some resource limits of the VM are rather low, but I don't think
the test hit any of them.

Have a nice day,
