AFAIK O_NOATIME is in kernel 2.6.8 and beyond. I could not find and
reports on a backport to 2.4.x. So this sounds like a bug in the kernel
and/or the filesystem. Other software that uses O_NOATIME (tar for
example) simply checks for the existance of O_NOATIME in <fcntl.h>, if
it is there, it will be used. At least the configure of aide tests if
files can be opened using this flag.

The fix to retry when opening with O_NOATIME fails (suggested by Pablo)
should work around this. So please try aide 0.11-rc2 when it is released.

Sincerely,

Richard van den Berg
