1 Redirecting I/O of setuid programs to NFS mounted FS
mostly fails because of the wrong credentials being passed
to the server.
2 Stale file handle problem:
sleep 10000 >file & // client
rm file;date >file // server
ls -l file // client again
ls: file: Stale NFS file handle
3 Negative dentry caching cannot be disabled.
IMO (1) should be fixed; it can't be that difficult because
many ac kernels don't have this problem. This bug is frequently
recurring. Maybe I'll fix it when I can find some spare hours.
(2) is difficult for me to estimate but this bug is annoying
at times.
(3) As I see it there are two possible solutions to handle
this neat feature when it is unwanted: put it under the "noac"
or other existing mount options regarding attribute caching
("acregmin=0" would work out best for me but not necessarily
for others). The alternative which is best IMO (but not acceptable
for 2.2.x I guess) is to create a new mount option. This would
also permit lengthening the negative dentry life time for those
who want it.
