fakeroot-hurd, fakeroot-tcp: small test to show failure

[Svante Signell]

Hi,

When looking for the EACCES problems with gpsd I found the following:

This small test reveals a bug in hurd (libdiskfs/dir-lookup.c,
trans/fakeroot.c, ...?):

touch test
chmod -w test

mkdir dir
ls -ld dir
drwxr-xr-x 2 srs srs 4096 Oct  8 17:06 dir

cp test dir/
ls -l dir
-r--r--r-- 1 srs srs 0 Oct  8 17:06 test

cp test dir
cp: unwritable ‘dir/test’ (mode 0444, r--r--r--); try anyway? y
cp: cannot create regular file ‘dir/test’: Permission denied

fakeroot-tcp cp test dir
cp: cannot create regular file ‘dir/test’: Permission denied
