comment Puppet causes endless restarts of CUPS (how does one prevent this)
+1 Much better than directly hacking at printers.conf! :D

comment How to do a file/dir exists conditional in Puppet?
Anything which causes the "require" to fail will give an error as the whatever has a failed dependency, whether using onlyif or unless... So technically it works but you'll get a lot of errors logged in your puppet logs...

comment How to do a file/dir exists conditional in Puppet?
@ddario Put the unique name (e.g. path) in the name of the exec -- so something like ``exec {"check for ${thing}": ... }'' and then it will be unique for each item.

comment Cent OS: How do I turn off or reduce memory overcommitment, and is it safe to do it?
"overcommit_ratio" has an important effect when using overcommit_memory=2 -- it determines the percentage of the physical RAM which is allowed to be allocated! So if ratio < 100 then you will leave some RAM unallocated, perhaps for disk cache or similar. The default ratio is 50% so you'll only use 50% of the physical RAM if you don't change this!

comment How can I tell which interface my Supemicro IPMI is piggybacking on?
If you can ssh into the host then you can also run ipmitool locally as something like "ipmitool raw ..." (numbers given in Supermicro FAQ entry linked to in the answer)

comment Exim drop vs deny for bad recipients
+1 for tarpit being the way to go. Legitimate occasional typos will still give the same result as normal but more slowly, whilst spammers will get bogged-down as you'd like.

comment Puppet : How to override / redefine outside child class (usecase and example detailled)
Unfortunately this method is now deprecated, as dynamic scope variables are being removed in a future version of Puppet -- see docs.puppetlabs.com/guides/scope_and_puppet.html An alternative method is to use variables defined by hiera on a per-node basis (and with a default set in a common data source). This does this all much more cleanly now :)

comment How to send the output from a cronjob to multiple e-mail addresses?
One thing to note -- use just a comma between addresses. Do not use a space as well, otherwise cron will log the address (probably in /var/log/cron or /var/log/daemon) as "UNSAFE" and will refuse to send to that list of addresses.

comment Linux clients on a Windows domains
If you want to have a Windows network with some Unix hosts it's a pretty good choice, but if you want to have full Unix support then there are other problems such as that the UIDs/GIDs won't match between any Unix users you have (say in LDAP) and the Unix emulation layer which Likewise Open provides on top of AD, unless you explicitly set the UIDs in LDAP to be the same as the numbers Likewise produces for you.

comment Home-brew automatic tiered storage solutions with Linux? (Memory -> SSD -> HDD -> remote storage)
Revitalising old questions is better than having then rotting with old and out-of-date information on them!
