All of the BSDs and some GNU/Linux distributions use Almquist for sh if not using a symlink to bash or dash. In fact, the first release of Slackware in 1993 had sh as a symlink to bash. I'm looking at the source code for the Bourne shell as included with UNIX SVR4 (circa 1988) and it's obvious that the version which Sun Microsystems/Oracle shipped with Solaris under the CDDL is a direct decedent. The license on the source code for the Bourne shell shipped with SVR4 clearly states: "THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T" Brandon Vincent ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I hope my prior comments weren't too off topic but a lot of people don't seem to understand the purpose for an enterprise distribution. DANE is a perfect example of this. Go poll the SMTP servers for any company on the S&P 500 and I can almost guarantee that 99.9% of them will not have TLSA records for DANE. It's a new/emerging technology. The same is true with DNSSEC (which is actually quite old). Enterprises are typically behind in the technology they adopt. Stability and reliability are paramount. This is where RHEL and CentOS come in. I know of a few companies listed on the S&P 500 who still have SSLv3 turned on to allow customers with old versions of Internet Explorer on Windows XP to connect. You can't simply assume everyone is using the latest technology. This is the reason IBM loves System z.

Go ahead and run a few of the S.M.A.R.T. tests. I can almost guarantee based off of your description of your problem that they will fail. badblocks(8) is a very antiquated tool. Almost every hard drive has a few bad sectors from the factory. Very old hard drives used to have a list of the bad sectors printed on the front of the label. When you first created a filesystem you had to enter all of the bad sectors from the label so that the filesystem wouldn't store data there. Years later, more bad sectors would form and you could enter them into the filesystem by discovering them using a tool like badblocks(8). Today, drives do all of this work automatically. The manufacturer of a hard drive will scan the entire surface and write the bad sectors into a section of the hard drive's electronics known as the P-list. The controller on the drive will automatically remap these sectors to a small area of unused sectors set aside for this very purpose. Later if more bad sectors form, hard drives when they see a bad sector will enter it into a list known as the G-list and then remap this sector to other sectors in the unused area of the drive I mentioned earlier. Basically under normal conditions, the end user should NEVER see bad sectors from their perspective. If badblocks(8) is reporting bad sectors, it is very likely that enough bad sectors have formed to the point where the unused reserved sectors is depleted of replacement sectors. While in theory you could run badblocks(8) and pass it to the filesystem, I can ensure you that the growth of bad sectors at this point has reached a point in which it will continue. I'd stop using that hard drive, pull any important data, and then proceed to run S.M.A.R.T. tests so if the drive is under warranty you can have it replaced.

Many > thanksNick Hi Nick, The service you are referring to is hostnamed [1]. hostnamed is designed to start on request and terminate after an idle period. Programs on your computer are probably querying the service to determine if your hostname has changed. This is normal behavior.
