 For me, I do !
 Although, any particular distro doesn't matter much.
 All of the BSD derivitives are very similar to each other, and
 all of the SysV derivitives are very similar to each other, with
 few exceptions.
 All I really care is that it's either SysV or BSD.

 Anything PLESK-ized though, is a convoluted problem.

 It's also worthwhile to reboot when making any system changes, just
 to prove that when a WinXXX "administrator" practices his first line
 of defense, that it will !!
 I've seen *nix where I needed to reboot for some reason, like physically
 moving the machine, and discovered that although it had been up and
 reliable for more than two years, it wouldn't, because of some small
 script error made in the forgotten past. ( it was a SCO-Unix box )

 One of the things forgotten, and sadly promoted by WinXXX is that
 a reboot is often a REAL bad idea.
 If a *nix box is alive, even if you suspect some corruption that *might* be
 cleared by a reboot, that reboot is often fatal.
 If it's alive, DO NOT REBOOT !! If it's alive, it can be fixed without rebooting, and
 very likely without any interruption to what it's still doing right. ESPECIALLY if
 one suspects a hardware failure !

 The ONLY time a Linux box *needs* rebooted, is a power failure, hardware
 replacement, or to replace the currently running kernel.
 On QNX, a reboot is unnecessary even then.
