usr/sbin vs usr/bin

usr/sbin vs usr/bin

[Patrick Venture]

Brad,

Reading the anti-pattern, I was going to start moving some things out
of sbin and into bin, I had considered why not just leave out the path
in the service file (as a step 1) - since systemd which just load the
first match in path, but the anti-pattern above indicates we should
use the full path in the service file, to make sure it runs the
correct one -- at least that's how I am paraphrasing it.

Please advise.

Patrick

Thank you!

Actually systemd doesn't go to the environment for this.  The
directories searched are described in systemd.service(5).

Just because this is the recommendation in the systemd.service man page:

"it is thus safe to use just the executable name in case of executables
located in any of the "standard" directories, and an absolute path must
be used in other cases. Using an absolute path is recommended to avoid
ambiguity."

Also fully qualified paths seem to be the convention when I look at
other linux distros.

thx - brad
