automated installs vs. drive imaging
What are the benefits and drawbacks of releasing using automated installs vs. drive imaging? For Windows I recognize there are concerns around SID generation when duplicating drives. Exist any kind of comparable concerns for releasing Linux using a photo?
I differ with several of the solutions below. If done appropriately you can take an Image and also load it on numerous systems making use of various hardware. Directly I've seen photos that sustain approximately 30 various systems.
My response to your inquiry is to make use of both approaches if you are really rectal concerning the production of a photo. Create the computerized install and afterwards sysprep the outcome. This will certainly bring about repeatable, self - recording photos.
Additionally, if you can contact the disk photo in its conserved state you can expand what gets on the photo by consisting of a script that can be run throughout sysprep. OR you can backup your system prior to taking a sysprep and afterwards expand it and also take a sysprep after.
I've done both approaches with excellent outcomes.
Pertaining to SID troubles, you need to constantly make use of Sysprep for a new photo (Although NewSID will certainly function), which will certainly settle any kind of SID concerns, However, there are various other applications which write GUIDs to the computer system registry which would certainly require to be cleansed. Off the top of my head Altiris and also WSUS are 2 that do this.
relies on what applications you will certainly install and also how much time you'll maintain the photo un - upgraded.
there is fairly a great deal of updates coming on a monthly basis so also after recovering box from photo you would certainly require to update it.
pertaining to SID - regarding i recognize it suffices if you create one-of-a-kind exclusive keys [ for ssh, https, tls eg for smtp/pop3 web servers etc ] this need to function penalty. additionally one-of-a-kind host name generation would certainly behave. this could vary relying on circulation, i'm primarily making use of debian and also didnt have any kind of troubles duplicating digital equipments with that said os.
Check out this inquiry which is really comparable :
(I asked it on stackoverflow.com a while earlier, when serverfault.com had not been around).
Drive imaging is much faster, yet your hardware needs to be really comparable for it to function. It is additionally tougher to tailor the photo, you would certainly require a base photo for an internet server, e-mail web server, etc With automated installs you can have all equipments install from the very same network area, yet make use of various manuscripts relying on what sort of web server you desire instead after that requiring to store and also create numerous photos.
