Black's questions

how can I add comments to logcheck ignore-rules?

Things I tried so far:

• # seems to match single # characters instead of starting a comment
• empty lines matches against everything
• $ matches against everything
• $^ seems to be an "impossible" regex, i.e. start of expression after end of expression

Is there a better way than starting lines with $^ ?

Is it guaranteed that lines starting with $^ will never match? What about performance?

Linux supports several types of watchdog hardware.

Is there a way to detect the available hardware watchdogs and load the appropriate kernel module (and "softdog" as fallback solution)?

I guess, just trying all available kernel modules is not an optimal solution.

EDIT:

I am surprised that modern systems do not have some kind of watchdog timer built into the CPU (at least no module is loaded for an AMD Athlon II). Are hardware watchdogs rare on consumer/prosumer systems?

I have a Ubuntu server with both samba and nfs-server.

The server does snapshotting for the exported directory and the samba server uses the snapshots to emulate shadow copies. ( vfs objects = shadow_copy )

When I export the same directory via NFS, the clients see the snapshot directories. Thus, a NFS client gets a messed-up directory listing containing lots of entries like @GMT-2012.01.31-13.00.01

How can I hide those subdirectories from NFS clients?

Thanks!
