Hello guys,
First of, thanks for your effort writing all this bunch of tests, It's
really helpful.
We are running LTP to test the correct behavior of a FileSystem
mounted in /mnt, however I installed ltp in /read/only/NFS/export/ltp.
I've already changed ltprun [1] so that it writes the failed log in
TMP (which should point to /mnt) instead of LTPBIN, but there are a
bunch of tests creating files in "." instead of TMPDIR, and for what
I've seen "." is actually LTPBIN for some tests which in our case is
read-only.
Also, I can't pass a base directory to run on to many of the tests,
take [2] as example where I patched it to write to TMPDIR.
Question:
Is running form a read-only path supported?
How can I make it create files only is /mnt instead of random places
trough the LTPDIR and /tmp?
Thanks
